Description

Blasting Apparatus for Forming a Horizontal Underground Cavity

The present invention is to blast an opening (a gap or a hole) on the wall surface of a predetermined position in the vertical hole of the vertical hole in the borehole, such as drilling and drilling vertically to obtain ground water, hot spring water, oil or natural gas existing in the ground The present invention relates to an explosive device used for opening blasting, which is one of the special blasting methods, and in particular, a catchment hole in an aquifer, such as a vein formed in jointing and stratification of a ground in a well, or a dielectric or gas layer in the ground Exploding the explosive device at the location of the opening, the outflow passage through which oil or gas flows out of the building, and expanding the opening through the concentration and continuous action of the explosive force in the horizontal direction to form and / or expand the horizontal hole in the ground of the vertical hole. The present invention relates to an explosion thrower for forming a horizontal hole and an assembly thereof.

When groundwater, hot spring water, petroleum, or gas leaks from a fluid layer (F) such as an underground aquifer, a dielectric layer, or a gas layer over a long period of time, crushed stone, clay, or debris together with the flow of fluid from the part of the outflow passage along the path taken into the well The impurity, such as the blockage, narrows the passage, and gradually the amount of fluid collected gradually decreases, or even the outflow passage is blocked, causing the well to be closed.

Accordingly, in order to increase the amount of fluid flowing out of the fluid layer F, such as an aquifer layer, a dielectric layer, or a gas layer, conventionally, the fluid in the perforated vertical hole H is first re-perforated separately from the surface or secondly. Two methods have been used in which explosives are placed and exploded in the air in the vicinity of the outlet, thereby regenerating by opening the outlet passage by the explosion pressure.

However, in case of re-punching separately, additional re-punching cost (7 to 150,000 won / m: proportional to the size of the drilling diameter) is additionally required, and it is very uneconomical because it inevitably involves the relocation and re-installation of additional facilities and facilities. In addition, in the case of exploding by placing explosives in the air of the perforated vertical holes (H), it is common that the vertical wall (H) is collapsed and most of the vertical holes (H) are rather depressed. For this reason, there is virtually no or very weak aperture blast effect, and it is difficult to expect the regeneration itself.

As a technique related to the underground blasting method for opening the opening of the perforated wall surface, which is the outflow passage of the fluid existing in the ground in the prior art, as shown in Figs. 1A to 1C, the ground primer 2 is simply loaded without a separate device. The explosive charge (1) to the hook (5) by the explosive bundle string (4) and connect the hook to the hook of the tow rope (6) by lowering the explosive into the underground vertical hole (H) by the tow rope The explosive is usually carried out after being placed in the air (= center of the drilled hole) in the vicinity of the opening of the rock joint, which is blocking the fluid flow path P by (I).

The explosive form described above is exploded in a state exposed to the outer space such as in the air or underwater and in the air (for example, air = explosion in the air). This is also called "open explosion".

Therefore, the blasting method according to the open explosion type is a form in which the explosive is placed in the air of the vertical hole H to explode in the open state, as shown in FIG. It is dispersed in the middle, and there is a large loss of explosive force into the empty space, and there is no directivity of the explosive force so that the equal pressure acts up, down, left and right, so that the pressure does not reach the blockage on the flow path (P) of the rock joint. Since it does not apply strong pressure and impact to the ground jointing and stratification, there is no opening effect, and in fact, there is no blasting effect or very weak phenomenon.

In addition, as shown in Figure 1c, the range of pressure distribution that the explosive force acts in the hole of the vertical hole (H) is widened to apply a wide range of external force to the empty wall of the perforated vertical hole (H), so that the wall surface of the vertical wall (H) It is difficult to expect the regeneration of the outflow passage of the fluid due to the deformation of the hollow wall caused by the deterioration of the perforated vertical hole (H) at all, or the closed hole, so it is only a conventional rudimentary technique without the effectiveness of the opening blasting.

That is, in the open explosion type as described above, the explosive force is exploded in the air of the vertical hole (H) so that the explosive force is opened to the upper and lower openings of the ball around the explosive. It is difficult to concentrate the explosive force to the point actually needed due to the large loss of the explosion pressure due to the wide distribution of the working pressure during the explosion.

In addition, the pressure at the time of explosion should be concentrated so that the pressure at the time of explosion can be blocked up to the blockage on the outflow passage of the fluid in the ground.However, the pressure at the time of explosion can be continuously applied due to the momentary dispersion of the uniform pressure (because of the open explosion type). Due to the short time, the required pressure is not enough to push out impurity (I) which blocked the flow of the fluid, so that it does not open the blocked outflow passage, but rather, the effect of opening blast is very weak due to the collapse or damage of the empty wall. Had.

In addition, it can not only be limited to the one blast effect of inserting the explosive device once into the ground in the vertical hole (H) and exploding once, especially the groundwater in the vertical hole (H) acts as an obstacle, thereby expanding the opening. Not only does the blasting effect decrease, but when descending to the blasting position of the ground speed in the vertical hole (H), the specific gravity of the explosive is slightly higher than the water, about 1.1 to 1.3. There was a big problem that the construction efficiency is low because of the slow.

In addition, it was difficult to apply explosive effects such as molding explosives due to the risk factors of explosion stability (concerns such as explosion, half width and safety accidents) due to water pressure and explosives loading in the state exposed to the outside. There was a problem in that an unsafe element of handling such as colliding with the ball wall of the vertical hole (H) during the lowering to the position to be left.

In order to solve the problems of the prior art as described above, the present inventors have a closed-type explosion type in consideration of the effect of the explosion and the principle of the force, such as directionality, concentration, persistence, protection of the explosive force during explosive explosion, In other words, the explosive effect of the explosives and the action of force to form a closed explosion in a confined space (e.g., the rifle's bullet is fired along the inner wire as an explosion of a primer in the chamber). Newly developed explosion-throwers to form and / or expand underground horizontal holes using principles.

The explosive radiator of the present invention forms a metal body having a constant cross-sectional thickness and a through-hole penetrating horizontally in the center of the body in the structure thereof, and a molding explosive and a delayed primer are mounted in this through-hole to It has an internal structure that allows the explosive force to concentrate in the horizontal direction.

In addition, by using an explosive radiator to change the direction of action of the explosive force in the horizontal direction, it is placed in the opening of the fluid outflow in the ball of the ground, and exploded once or several times to open or enlarge the outlet of the opening intensively and repeatedly Propose a special blast help mechanism that collects more water, oil or gas, ie the function of an exploding radiator and the explosive effect of molding explosives to form underground holes and / or to expand openings. It is done.

As used herein, the term “opening portion” refers to a crack formed in a rock joint or layer in a perforated vertical hole H, or a hole through which fluid flows out. It is preferable to interpret it as meaning.

In addition, the "explosion thrower" is a blasting device in which a through-hole penetrating horizontally in the center part is formed and encloses the through-hole, and a molding explosive device is loaded in the through-hole. It refers to an explosive device that is inserted into the inside of the weaver H and mounted at a predetermined position in the ball to explode, thereby converting the explosion pressure during explosion horizontally, which may also be referred to as "ground cannon".

"Shaped charge" is an explosive that is used to make the area of the portion to be broken small, and is formed into a conical shape in which the shape of both ends of the explosive is concave into the center. It means explosives to achieve a concentrated effect to concentrate to, and in some cases it may be provided with a conical metal liner to exhibit a strong concentrated breaking force.

The "closed pressure blocking ring" is loaded in the insertion groove of the body of the explosive radiator so as to act in a predetermined direction to exert the explosive pressure discharged from both ends of the through hole of the body of the explosive radiator. , It means a ring that is blocked from the outer peripheral space and confines the explosive force at the time of explosion to the concentration of the explosive power, and the "radiation ball" releases the explosive pressure during the explosive explosion. It means both ends of the through hole formed in the center of the body.

"Opening blast" refers to a type of special blasting that opens a closed hole or vein in a rock; and "opening pressure" refers to a blockage in a fluid flow path by impurities. The force that explodes to the location and opens the blocked passage.

The Neumann effect, also known as the "Munro effect", refers to the effect that the explosive force is concentrated in the center when explosives explode and detonates explosives with a conical or hemispherical concave metallic liner. Then, when the liner collapses, the metal particles are released to form a jet, which hits the target and creates a deep hole in the center, which is applied to a special drilling operation.

An object of the present invention is to induce a closed explosion in a limited chamber space that is closed and blocked with the outer space in order to concentrate the range of the explosive force in the ground, so that the pressure at the time of explosion is perpendicular to the vertical drilling hole, that is, the horizontal direction By directionality and concentration to act as a function, it is possible to expand and blast stable openings while preventing the collapse of the perforated wall, and to explode the radiator and its assembly to form underground horizontal holes that increase the efficiency and safety of construction. To provide.

Another object of the present invention is to reduce the amount of fluid flowing out during long-term fluid collection in the existing wells of groundwater, hot spring water, natural gas and petroleum boreholes, the passage is blocked or depleted, or if the effect of drilling is insufficient or insufficient The present invention provides an explosive spinner and an assembly thereof for forming a highly efficient underground horizontal hole that regenerates a well by opening an existing sealed fluid passage without increasing re-perforation by using the perforated hole. .

Another object of the present invention is to develop a new borehole of groundwater, hot spring water, natural gas and petroleum boreholes. The present invention provides an explosive radiator and an assembly thereof for forming underground horizontal holes which increase the probability of the mining of the fluid because the mining method is formed in the radial area mining type rather than the point mining type.

Another object of the present invention is to drill the ground indiscriminately for the extraction of groundwater, oil or gas mining to minimize the pollution of the environment through the hole, and also to increase the underground horizontal hole in consideration of the environment to suppress the perforation To provide an explosive thrower and its assembly for forming.

DESCRIPTION OF EMBODIMENTS The technical configuration of an explosive radiator for forming underground horizontal holes of the present invention will be described with reference to the accompanying drawings.

As shown in Figs. 2A to 2D, the explosive spinner of the present invention has a through hole 11 formed horizontally at a predetermined position in a central part, and a connecting ring 12 is provided at each of upper and lower ends to surround the through hole. Metal body 10 having a cross-sectional shape of a predetermined size, connecting means 50 provided on at least one side of the upper and lower ends of the body 10 connected to the traction line 70, and the through hole of the body The delayed primer 23 mounted in the 11 is composed of the molding explosives 20 loaded so that the explosive force of the molding explosives 20 mounted in the through holes is concentrated in the horizontal direction through the through holes 11. It is characterized by one.

3A to 3D, a tubular insertion groove 14 is formed on the body 10 spaced apart from the through hole 11 by a predetermined interval, and the branch primer is formed in the insertion groove 14. (31, 32) is characterized in that it further comprises a configuration in which the explosives 30 loaded with the loaded pressure blocking ring 40 of the plastic material in sequence.

In addition, the liner 22 of the metallic material is additionally included at the end of the molding explosive 20 is characterized in that the configuration.

In addition, as shown in Figure 4, by connecting the plurality of bodies 10 by a predetermined interval by the connecting means 50 is characterized in that it provides an explosion-radiator assembly capable of a multi-stage explosion.

The blasting principle of the explosive radiator for forming the underground horizontal hole of the present invention having the above characteristics will be described.

In order to drill a horizontal auxiliary hole in a vertically perforated wall surface, it is essential to change the direction of the dynamic force so that the explosive force acts in a direction perpendicular to the hollow wall surface. By the way, in the depths of several tens of meters to thousands of meters underground, any mechanical device such as a drilling machine is impossible to redirect the force in a right direction.

Thus, the present invention provides an empty wall under ground, such as when a rifle (or cannon) fires with a direction toward the point target, which is a point of impact along the inner line of the closed barrel (or barrel), along the inner line of the closed barrel (or barrel). A horizontal through-hole is formed in the center of the body of a high-strength metal body having a predetermined cross-sectional shape so that the explosive force of the explosive can be switched in the horizontal direction so that the destructive force in the perpendicular direction is applied to the The explosive force is formed by attaching explosives to the center of the through-holes to explode. In the closed state, the explosive force is directed and is discharged and concentrated in the horizontal direction where the through-holes are formed. And / or use the principle of extension.

In addition, it is applied to the explosive effect by the explosive molding, that is, the Neumann effect (also called the "Con effect") to apply intensive pressure to the necessary wall part (applied to the antitank high-bombs that penetrate the iron armor of the tank). Explosive pressure leakage by adding a configuration of a closed pressure blocking ring that concentrates the explosive force to the central part and closes to the hollow wall from the body of the explosive radiator so that it acts as a hedge of explosive power in case of explosion of molding explosives. It is to make a strong and concentrated explosive force for a certain time in a certain direction without.

That is, the present invention is an explosion spinning machine in which a molding explosive is loaded in a central through-hole of the body of the present invention at a point where fluid flows out at a ground speed in a vertical hole (H) of a drilled / drilled hole or a high probability of leaking. It is an excellent technology to form underground horizontal holes by converting the explosive energy generated at the time of explosion to the transverse pressure perpendicular to the drilling direction and acting the transverse pressure on the ball wall surface.

The main configuration of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 2A, the body 10 has a through hole 11 having a predetermined diameter horizontally in the center of the left and right end portions thereof, and the connecting ring 12 is provided at the upper and lower ends thereof so that the through hole 11 is provided. ), The cross section of the left and right sides of the central portion of the body 10 having a constant cross-sectional shape, preferably a brown-shaped structure, and a through hole 11 is formed in order to double the charge and the loading speed. It is manufactured integrally with a factory product so as to have a shape of a protruding portion close to the wall surface of the weaver H.

As shown in Figure 2b, the reason that the shape of the body 10 is formed in the shape of an egg, the end is formed in a round shape while maintaining the center of gravity when inserted into the vertical hole (H) in contact with the ball wall surface By reducing the area, the collision is reduced, and the friction resistance with the fluid between the vertical and horizontal movements (for example, the groundwater in the vertical hole H) is reduced in the perforated vertical hole H, thereby reducing the buoyancy of the ground water. This is to allow to fall to some extent in the vertical hole (H).

Of course, as the cross-sectional shape of the body, various forms such as conical, hexagonal or octagonal can be modified. However, since these are only design changes, it is most preferable to make the egg shape as described above.

On the other hand, the body 10 itself is a metal material of high strength and has a constant cross-sectional shape is that the molding explosive charge 20 is loaded in the through hole 11 in the future, the body 10 surrounding the through hole in the explosion when the explosion force In order to withstand and not to break, and also to allow the body 10 to be recovered and recycled after the opening blasting is completed.

The reason why the left and right end surfaces having the through holes 11 formed horizontally in the central portion of the body has a shape of a protrusion that is close to the wall surface of the vertical hole H is because of the molding explosives loaded in the through holes 11. The explosive force is applied at a close distance to the hollow wall surface, and the range of the explosive force projected onto the hollow wall through the through-hole 11 is limited to a minimum range, that is, the explosive force is applied to a smaller range, thereby reducing the concentration of the explosive force. This is to promote.

On the other hand, the width of the body 10 is determined according to the size of the perforated vertical hole (H) is formed in the size of approximately 80 to 90% of the diameter of the vertical hole (H), which is perforated perpendicular to the ground This is because the insertion of the body into the vertical hole (H) should be easier than the diameter of the drilled drilling.

For example, since the diameter of the drilled hole drilled for collecting ground water, oil or gas is usually within 100 to 2,000 mm, the width of the body is smaller than 80 so as to facilitate insertion into the vertical hole (H). It is manufactured to have a width in the range of ˜1,800 mm, and the weight of the body 10 has a range of 50 to 500 kg (the size of the explosive radiator is also varied depending on the size of the perforation), and the through hole. It is preferable that the size of (11) has Φ50 mm to 250 mm.

The inner space of the through-hole 11 serves as a kind of chamber for loading the branch primer 23 and the molding explosive 20, which are later mounted, and both openings other than the space in which the explosive is loaded are loaded. It acts as a spinneret 13 to induce the explosive force of the molding explosives. Therefore, since the explosion in the closed state in the through-hole is possible, the explosive force is directed and discharged in the horizontal direction, whereby the explosive force can be concentrated.

The connecting ring 12 is fixed to the body 10 at the upper and lower ends of the body, respectively, the connecting ring 12 is welded to the outside of the body by fitting the connecting means 50 to the connecting ring Although not shown, it is to be noted that it is possible to drill a horizontally penetrating hole (in this case, the weight of the body becomes light) near the end of the upper half or the lower half of the body 10 to be sewed while penetrating the hole.

On the other hand, as shown in Figs. 2B and 2C, an insertion hole 15 is formed from the predetermined position of the upper half surface of the body 10 to the center of the through hole 11, and the line 24 is formed through the insertion hole. It is possible to be drawn into the through hole 11 and connected to the branch delay primer 23 to be loaded into the molding explosive 20. Also, the angle line 24 may be installed through both sides of the through hole 11. Reveal

That is, one end of each wire 24 is connected to the delayed primer 23 and loaded with the molding explosive 20 in the center portion of the through hole 11, and the other end is drawn out of the insertion hole 15 to It is connected to the blast bus immediately before inserting the body into the weaver (H).

On the other hand, the loaded delayed primer 23 is to use the MS delayed primer or LP delayed primer, etc., a gap is formed between the wires 24 connected to the delayed primer and drawn out to the outside of the insertion hole 15. When the body 10 is inserted into the vertical hole (H) later, groundwater or the like penetrates into the gap, and thus, the gap between the wire 24 and the insertion hole 15 is prevented from occurring during the explosion of the branch primer. To seal.

On the other hand, as shown in Figures 2b and 2c, the forming explosives 20 are explosives formed with a conical groove 21 in which the cross-sectional shape of the left and right ends thereof is recessed toward the center portion, and when the gas is exploded, It should be able to operate with minimum effective energy considering efficiency maintenance and securing breakdown force, and should have the breakdown force without damage of the radiator body in the space of limited through hole, so the dosage should be in the range of 0.1 ~ 1㎏. Do.

The reason for the range of the loading amount is that when the loading amount of the molding explosives loaded in the through-holes is less than 0.1 kg, the strength and gas pressure of the explosive force are lower than the standard value, and the effect of the expansion wave is less than expected. If the weight is 1kg or more, there is a problem that the body of the explosive radiator is destroyed or the hollow wall is destroyed.

The reason why the conical groove 21 in which the cross-sectional shape of the left and right ends of the molding explosive is recessed toward the center is formed so that the explosive force is strongly concentrated at the center of the conical groove by the vector sum of the forces due to the Neumann effect when the explosive is exploded. To do that.

That is, as in the case of the antitank high-bombs penetrating the iron armor of the tank, which is a technique to which the Neumann effect is applied (penetrating up to 35 cm), as shown in Figs. 2C and 2D, a horizontal nuptial hole (explosive charge) While forming a conical hole formed by the explosion, the explosive force (opening pressure) acts strongly into the rock or the joint of the rock, allowing it to continuously penetrate deeply (a range of influence: several tens of meters), thereby preventing impurity (I). The outflow passage (P) that was pushed out is opened, and the explosive force makes the fluid flow smoothly by forming a horizontal hole in the ground by expanding the outlet surface of the empty wall through which the fluid flows out.

On the other hand, as described above, the destructive force due to the Neumann effect is concentrated at the time of explosion of the molding explosives 20 having the conical grooves 21 formed therein, but a predetermined blasting effect may be expected, more preferably, FIGS. 2A to 2. As shown in 2c, it is evident that the funnel-shaped metal liner 22 may be additionally attached to the conical grooves 21 at the left and right ends of the forming explosives 20 to concentrate the strong breaking force. The liner is generally conical in shape and made of steel or copper, approximately 1 mm thick.

On the other hand, when the loading of the molding explosives 20 to the body 10 is completed, the carver 25 made of glass or plastic is adhered to the both ends of the through hole by an adhesive and sealed. This is to minimize the effect of the loaded molding explosives 20 from the hydraulic pressure.

On the other hand, Figure 3a is a view showing a modification of the body shown in Figure 2a, spaced apart from the through hole 11 at regular intervals on the body 10, the tubular symmetrically on both the left and right sides around the through hole 11 Insertion groove 14 of the additional is formed, the circular propelling charge 30 and the plastic pressure closing ring 40 made of a plastic material loaded from the bottom of the insertion groove 14 to load the delayed primers (31, 32) sequentially The structure of the body to be loaded is shown.

In addition, FIG. 3B shows insertion holes 16 and 17 penetrating from the bottom of the insertion groove 14 to the upper half surface of the body 10. 31 and 32 and the wires 33 and 34 connected to the blast bus are loaded with the propelling charge 30 positioned at the bottom of the insertion groove 14.

Such a structure is a modified form of the structure of the body 10 shown in Fig. 2b, which is after the first explosion of the propelling charge 30, the molding explosives 20 are second exploded, It has a two-stage body structure.

The propelling charge 30 is loaded with the primers 31 and 32 at the bottom of the insertion groove 14 and is firstly exploded to push the plastic pressure blocking ring 40 made of plastic toward the coplanar surface. Although shown in the form of a circle, as shown in 3a, the unit charges may be arranged at regular intervals, and the unit charges may be wound with a depletion line (not shown) to detonate.

The dosage is in the range of approximately 10 to 30 g, but the dosage is loaded in a small amount because the dosage is enough to be brought into close contact with the wall surface by pushing the closed pressure blocking ring 40 after the explosion.

As shown in FIGS. 3B and 3C, the closed-pressure blocking ring 40 is formed in a ring shape made of plastic material and is inserted into the insertion groove 14 while the propelling charge 30 loaded on the bottom of the insertion groove 14 is loaded. ) Is projected from the insertion groove 14 by the explosion of the propulsion charge 30, and is mounted in close contact with the empty wall, the gap between the through hole 11 and the empty wall between the body 10 and the empty wall surface It is a member which separates a space part from the space part of the upper and lower sides, and forms independent closed space part S.

The closed pressure blocking ring 40 is a fence that is temporarily trapped so that the explosive force discharged from the spinneret 13 during the explosion of the molding explosive 20 does not leak to the upper and lower openings of the ball (that is, the outside of the closed pressure blocking ring). Because of the function, the explosive force enables the concentration and continuous action of the explosion pressure toward the rock joint or stratification in the closed space (S), and also has the function to make the hydraulic pressure blocking function and the safety explosion.

As shown in Figure 3c, this closed pressure blocking ring 40 is made of a suitable size so as not to escape from the insertion groove 14 in forming a closed space (S) between the body 10 and the hollow wall. When the explosion pressure in the sealed space S reaches the maximum pressure in the middle of expanding the opening of the hollow wall through which the fluid explodes during the explosion of the molding explosive 20, the pressure blocking ring 40 of the plastic material 40 Is broken and scattered.

As shown in Fig. 3d, when the explosive action is completed, the fistula is formed in the hole wall surface opening in the ground where the fluid flows out, and the opening is intensively expanded to form a horizontal expansion hole to smooth the flow of the fluid. .

This structure is more explosive in the form of explosive in the state of being cut off from the outer space than shown in FIG. The opening pressure acts deep in the passage to push out the impurities (I), thereby revealing more effective opening blasting.

On the other hand, the connecting means 50 is a structure that is connected between the body 10 and the body 10 and connected to the tow line 70 of the body 10 and the towing device (W ₁ ), between the body 10 Consists of a structure of a predetermined length of the chain ring 51 is connected so as not to twist the upper and lower ends, it is a structural member connected to the end of the connecting ring 12 and the traction line 70 formed on the upper and lower ends of the body.

On the other hand, the blasting bus 60 is wound on the ground winding machine (W ₂ ), but before the body 10 loaded with the molding explosive charge 20 is inserted into the vertical hole (H) to the outside of the body (10) Connected to the drawn wires 24, each of which is inserted into the chain ring 51, which is a connecting means of the explosive radiator, and is inserted into the ground in the vertical hole H together with the explosive radiator from the winder W ₂ . When the body is set at a predetermined position in the well of the ground, the end of the blasting bus 60 wound around the winding machine W ₂ is connected to the blasting machine.

A first embodiment of an explosive radiator for forming underground horizontal holes of the present invention will be described.

In this first embodiment, as the structure of the body 10 is shown in Figure 2a, the through hole 11 is simply formed in the center of the body, and the connecting ring 12 is fixed integrally to the upper and lower ends of the body. As a structure, the molding explosives 20 equipped with the branch delay primer 23 and the metal liner 22 are loaded in the through hole 11, and each wire is connected to the blasting bus 60, and the blasting bus is connected to the blasting machine. It is an embodiment to be exploded.

One end of each wire 24 is drawn out into the through hole 11 through the insertion hole 15 of the upper half of the body, and is connected to the branch primer 23 from the outside of the through hole to form the through hole 11 together with the molding explosive 20. It is loaded in the center of the inside, the other end is installed on the ground connected to the blasting bus 60, the blasting bus 60 is released from the winding machine (W ₂ ) as it is introduced into the well of the underground with the explosive radiator. Since other structures are as described above, detailed description thereof will be omitted.

This embodiment is formed in a one-step explosion form, the explosive force of the molding explosives 20 simply breaks the cover 25 attached to both ends of the through hole 11 and explodes in the horizontal direction perpendicular to the vertical direction of the perforation. The embodiment is concentrated and discharged.

As another embodiment of the present invention, a second embodiment will be described.

This second embodiment is different from the first embodiment in which only the through hole 11 is formed in the body 10, and the structure of the body 10 is slightly modified. As shown in FIG. 3A, the body 10 In addition, a tubular insertion groove 14 spaced apart from the through hole 11 at regular intervals is formed symmetrically on both left and right sides of the through hole 11, and the insertion groove 14 is shown in FIG. 3B. As described above, the circular propelling charge 30 loaded with the delayed primers 31 and 32 and the closed pressure blocking ring 40 made of plastic are sequentially mounted, and other configurations are similar to those of the first embodiment. Note that it is the same.

This second embodiment is a two-stage explosion, as shown in Figure 3c, the closed pressure blocking ring 40 by the first explosion of the propellant charge 30 loaded in the bottom in the insertion groove (14) ) Is in close contact with the hollow wall surface of the ground speed to form a closed space (S) between the body 10 and the hollow wall surface, the molding explosives 20 is an embodiment in which the second explosion.

This second embodiment is different in that the explosive force of the molding explosive 20 is not emitted to the outside by the closed pressure blocking ring 40 in the explosive force is radiated in the horizontal direction perpendicular to the vertical direction of the drilling. Therefore, it can be said that more effective blasting in opening blasting than in the first embodiment.

These first and second embodiments have a form of exploding by attaching a molding explosive 20 additionally provided with a funnel-shaped metal liner 22, each of which strongly strikes an opening on the hollow wall surface of the ground. Of course, it is possible to form a horizontal hole.

On the other hand, in the form of connecting a plurality of explosive radiators of the present invention, as shown in Figure 4, a multi-stage explosion that is installed by connecting a plurality of bodies 10 at regular intervals by the connecting means 50 As an embodiment of the radiator assembly, the blast emitters of the next stage are sequentially positioned in the opening of the point where the horizontal hole in the ground is required to be formed to repeatedly explode, thereby further increasing the blasting effect.

The use of the plurality of explosive radiators is divided into two types, the first of which is a plurality of explosion radiators are connected to the connection means 50 at regular intervals of each of the through hole 11 of the body 10 This is a third embodiment in which the directions are provided in the same direction.

This third embodiment is an embodiment used to repeatedly explode the same point on the hollow wall in the ground, and is used when the passage through which the fluid flows is confirmed.

Second, the explosive radiators installed by connecting a plurality of them at regular intervals to the connecting means 50 are sequentially installed at 90 ° angles in the direction of the through-hole 11 of the body 20 from the lowermost explosion radiators. It is the fourth embodiment made possible.

This fourth embodiment is an embodiment that explodes the hollow wall in the radial direction under the ground speed, and is used to increase the probability of the fluid leaking out when the passage through which the fluid flows is uncertain.

That is, in each of the third and fourth embodiments, the wires 24 coming out of the body from the branch primer 23 loaded in the molding explosives 20 and loaded in the propelling charge 30 to be described later are loaded. Angle lines 33 and 34 coming out of the delayed primers 31 and 32 are connected to the blast bus 60 which is released from the winder W _{2 on the} ground before the explosive radiator is inserted into the ground in the vertical hole H. It is installed, each wire installed in each explosion radiator is inserted into the vertical hole (H) while being connected to each blast bus (separate blast bus is connected to each blast).

At this time, the blast bus 60 does not intersect the through hole 11 in which the molding explosives 20 are loaded, so that the connecting means 50 is located at an outer position of the body 10 at a 90 ° angle with the direction of the through hole 11. It is preferable to extend through each of the chain ring 51 of the parenthesis.

This is to prevent the explosion by preventing the blast bus 60 connected to the explosion radiators from being twisted or disconnected while being not affected by the explosive force discharged into the through hole 11.

On the other hand, the constant distance by the connecting means, that is, the interval between the adjacent upper and lower explosion radiators may have a distance in consideration of the net width (responsive explosion), preferably at least 1m intervals.

The opening blasting by the explosive emitters (ground cannons) of the present invention configured as described above has a limited range of the explosive force at the time of explosion due to the directionality and persistence of the explosive force and the concentration of the explosive pressure due to the Neumann effect. By concentrating on the inside, it is possible to minimize the collapse and depression of the hollow wall while forming horizontal fistulas in the ground, and the explosive force acts the opening pressure deeply into the opening to push out impurities on the outflow passage.

In addition, bubbles (bubbles) generated by the explosion gas projected into the opening at the same time as the explosion is injected into the opening and exits through the blocked outflow passage, whereby the siphon effect of drawing the fluid on the outflow passage together Function to facilitate the outflow of fluid.

The assembly of such an explosive radiator is repeatedly repeated several times by connecting, loading, towing and placing the plurality of bodies 10 as many times as necessary (less than 10 preferably) at regular intervals for continuous construction and repeated use. By exploding by maximizing the opening probability of the outflow passage of the fluid in the rock joint, as well as improving the efficiency of construction, it can be summed up as a "soft underground cannon".

A technical configuration of the blasting method for forming underground horizontal holes using the explosive radiator having the above configuration and its assembly will be described with reference to FIGS. 4 to 9.

The blasting method of forming a horizontal horizontal hole by using the explosive radiator of the present invention is a horizontal piercing through the inside of the central portion of the body 10 of the egg-shaped explosive radiator made of metal on the surface of the ground near the well where the fluid is collected from the ground speed.

In addition, in the blasting method of forming the underground horizontal hole by using the explosive radiator of the present invention, the blasting step is first loaded in the tubular insertion groove 14 spaced at regular intervals from the through hole 11 of the explosive radiator in the blasting step. The primary explosion of the primer and the propulsion charges 30 is carried out, and the closed pressure blocking ring 40 made of plastic, which is the color of the propulsion charges, is brought into close contact with the outer wall of the perforated hole in the ground, and then cut off from the outside. And a second explosion of the forming explosive (20) mounted in (11).

In the blasting step, when the explosion is performed using the assembly of a plurality of explosion radiators inserted into the ground of the vertical hole (H), it explodes several times in the same position or radially while descending sequentially from the explosion radiator installed at the lowest end. It is characterized by.

That is, in the blasting step, a plurality of explosion radiators installed in the ground by being connected to the connection means 50 at regular intervals are each stepped by an explosion radiator installed in the direction of the through hole 11 of the body 10 at the same angle. As it descends, it explodes repeatedly at a constant position to concentrate the explosive force in the openings on the underground walls.

In addition, it is characterized in that the blasting step 20 by igniting the delayed primer in the ground by the remote controller during the blasting step.

The blasting construction procedure for forming underground horizontal holes using the explosive radiator of the present invention having the above configuration will be described.

First, as shown in Figs. 4 and 5, the through-hole of the body 10 of the explosion thrower by mounting the body 10 of the explosion thrower manufactured and transported at the factory to the holder on the bogie or the carrier (C) 11 is loaded with a delayed primer 23, a line 24, a molding explosive 20, and a metal liner 22. At this time, according to the shape of the body 10 of the explosive radiator, the propellant 30, the pressure blocking ring 40, the delayed primers (31, 32) or the legs (33, 34), etc. are additionally loaded.

These loading methods insert one end of the wire 24 into the wire insertion hole 15 penetrating from the upper half of the body 10 to the center of the through hole 11, and draw it out to the outside of the through hole 11. 23) and loads the delayed primer into the central part in the through hole 11 together with the forming explosive 20. On the other hand, the other end of each wire is drawn out of the insertion hole to the outside of the body.

Similarly, one end of each wire (33, 34) is inserted into the wire insertion hole (15) penetrated into the insertion groove at the upper half of the body (10), and drawn out to the outside of the insertion groove, and connected to the delayed primers (31, 32). The delayed primers are loaded to the bottom of the insertion groove together with the propelling charges 30, and is colored with the pressure blocking ring 40. On the other hand, the other end of each wire is drawn out of the insertion hole to the outside of the body.

After the explosive charge is loaded as described above, the sealing material is filled and sealed between the gaps between the wires 24, 33, 34 and the insertion holes 15, 16, 17 drawn out from the insertion hole of the body, and the through hole ( All the loading is completed by adhering the cover 25 to the stepped portions of the body of both ends of 11) with an adhesive.

After the explosive charge is completed on the body of the explosive emitter as described above, as shown in Figure 5, by using a trolley or carrier (C) to move the explosive radiator to the position of the well connected to the traction line of the traction device (W ₁ ) Hang the hooks on the top of the explosive thrower on the hooks.

After suspending the first explosion thrower, move the next explosion thrower to the well position and connect the chain link to the lower link of the upper explosion thrower.The lower link of the lower explosion thrower is connected to the lower link of the linked chain. Connect and suspend the link.

As described above, by repeating the connection between the traction line and the explosion radiator of the traction device (W ₁ ) and the connection between the explosion radiator and the suspension operation, several explosion radiators are suspended on the upper portion of the vertical hole (H).

As shown in Fig. 6, the lowermost explosive radiator suspended on the upper part of the vertical hole H is lowered to stop at the inlet position of the vertical hole H of the well, and the angle lines drawn out from the upper half of the body of the explosive radiator are removed. Connected to the blasting bus 60, the explosive radiator after the connection work is inserted into the ground in the vertical hole (H) to descend, and then placed in the suspended explosion radiator at the entrance of the vertical hole (H) again, Again, the connection work connecting the wires and the blast bus and the step of inserting and descending into the ground in the vertical hole (H) are repeatedly performed.

At this time, the blast bus 60 is released from the winder (W ₂ ) to be introduced into the ground speed along with the body 10 of the explosion-radiator descending to the lower portion of the ground speed in the vertical hole (H). On the other hand, in the case of the assembly of a plurality of explosive radiation emitters because each wire is installed in each of the blast bus 60 to be connected, that is, because several blast buses are connected to the blasting device, it is particularly note that they are well connected to install them shall.

When the wires of the explosive radiator have completed the connection work with the blasting bus, as shown in FIG. 7, the blasting apparatus W ₁ is suspended as it is suspended and inserted into the ground in the vertical hole H. Loosen the tow line 70 and lower the explosion radiator inserted in the vertical hole (H) to the opening position of the required point in the underground. At this time, the blast buses 60 connecting the wires 24, 33 and 34 are released together to the descending position of the explosive radiator, and are introduced into the ground. When the explosive radiators are set at the position of the opening to be exploded, the blast buses are discharged. To complete the blast preparation.

The next step is the blasting step. As shown in Figs. 4 and 8, the explosive force 20 is exploded by igniting the branching primer with the blasting machine, and the explosive force is discharged to be concentrated in the horizontal direction at both ends of the through hole. By forming horizontal nipples on the cavity walls, the openings, which are the outflow passages of the fluid, are blasted.

In the case of explosion using the explosive radiator of the first embodiment shown in FIG. 2A, only the explosive charge 20 needs to be exploded. However, in the blasting method, a wire may be installed to ignite by the blasting machine. It turns out that the explosive molding 20 may be exploded by igniting the delayed primer by using a remote controller on the ground.

On the other hand, in the case of explosion using the explosive radiator of the second embodiment shown in FIG. 3a, first, the propelling charge 30 is first exploded, and the closed pressure blocking ring 40 is first brought into close contact with an empty wall to block the outside world. In order to explode the molding explosive 20 secondly, each wire must be installed and ignited by a blasting machine.

The first embodiment and the second embodiment are the same position when sequentially exploded by only one explosion radiator, or when exploded using the assembly of a plurality of explosion radiators, sequentially descending from the lowermost explosion radiator Or you can explode radially again, there are two types of explosions.

That is, when the through-holes 11 of the body 10 of the explosive radiators equipped with the molding explosives of the third embodiment shown in FIG. 4 are installed in the same direction for each of the explosive radiators, the flow point of the fluid is surely checked. If possible, it is used to concentrate the explosive force by repeatedly exploding at the same position of the underground wall.

In addition, although not shown, as a fourth embodiment, the through-holes 11 of the body 10 of the explosion throwers equipped with a molding explosive are alternately installed at 90 ° angles from the top explosion throwers, respectively, It is used to explode in the radial direction from the hollow wall surface of the ground if the outflow point is not identified correctly.

These third and fourth embodiments will be used in the form of repeatedly exploding as many times as the number of explosives.

As shown in Fig. 9, after the explosion of the explosive radiator is completed to form a horizontal hole in the underground, the explosion thrower and the winding machine W ₂ supported by the tow line 70 located in the ground in the vertical hole H. The blast buses 60, which are pulled and released into the ground, are lifted out of the ground surface to recover the body of the explosive radiator, and can be used again by loading molding explosives for re-blasting.

As described above, the blasting method for forming underground horizontal holes by using an explosive radiator has a concentration function of explosive force, a continuous function of explosive force, and a siphon effect of drawing fluid together by bubbles generated by gas or water. By inserting the explosive radiators into the ground velocity in the vertical hole (H) and exploding, the projection range of the explosive force concentrates within a limited range of the perforated wall of the ground to form a horizontal fistula, and the opening pressure deeply into the opening by the explosive force. This action pushes out impurities on the outflow passage to facilitate the outflow of the fluid.

The blasting method for forming underground horizontal holes using the explosive radiator as described above is an enclosed blasting type having an equilibrium due to the action and reaction of the force and the direction of the explosive force, and the explosion effect and the Neumann effect of pressure concentration. By blasting by application, by providing the required explosive power with a minimum charge, the explosive force is concentrated on the opening of the continuous hollow wall surface of the vertical hole (H) to expand the opening.

On the other hand, conical fistulas, ie, horizontal expansion holes, are formed horizontally on the hollow wall surface of the ground wall by the explosive force to prevent the strengthening and collapse of the supporting wall of the ground wall in the ground, and the explosive force is the minimum required area of the hollow wall (jointing and Due to the mechanical properties of the rock acting on the stratification, etc.), the vertical hole (H) is prevented from being collapsed or collapsed.

In addition, as in the case of antitank heavy bombs penetrating the iron armor of tanks applied to the explosive force of the molding explosives (penetrating up to 35 cm), the opening pressure in the ground (rock) or ground (rock) of the ground velocity This powerful action continuously penetrates deeply into the outflow passage of the fluid (impact zone: several tens of meters), and expands the existing opening for the purpose of opening blasting and secures the space again, allowing the fluid such as groundwater and petroleum to be regenerated to reclaim the well. do.

By forming conical horizontal expansion holes (secondary holes) on the limited perforated wall surface of the ground, the depression and collapse of vertical holes is prevented in advance, and the loss of explosion pressure or damage to the holes, such as exploding in the air, are prevented. Therefore, even a small amount of explosives of about 20% can have a greater effect.

In addition, by providing explosives loading, insertion of vertical explosives, insertion of vertical holes (H), and speed of work, and ease of installation, blasting can be performed several times with one loading. Phosphorus recycling is possible to ensure the effectiveness of the opening blast forming the underground horizontal hole of the present invention.

The present invention configured as described above provides a blasting method for forming underground horizontal holes by using an explosive radiator to completely solve the disadvantages of the prior art, thereby minimizing the range in which the explosive force acts on the continuous hollow walls of vertical holes. By concentrating the explosive force in a limited chamber space in the through-hole of the body or in a closed state that is closed and blocked with the outside world, thereby concentrating the explosive force in a direction perpendicular to the drilling direction and By maintaining continuous action (double the duration of pressure), strong and intensive pressure is applied to the required wall part in the ground, which prevents the collapse of the ball wall surface of the vertical hole and enables the opening blasting to form a stable underground horizontal hole. have.

In addition, the present invention by continuously acting the maximum explosion pressure with a minimum amount of charge, the groundwater in the vertical hole (H) in the closed area serves as a water cannon at the same time the high pressure gas and high pressure water at the same time the minimum explosion maximum explosion pressure It provides and maintains the effect of delivering the opening stress (influence up to several tens of meters during the hydraulic action) for a long time deeply in the outflow passage of the fluid, which has the effect of smoothing the outflow of the fluid.

In addition, the present invention in the existing wells of groundwater, hot spring water, natural gas and petroleum borehole during the long-term fluid collection, if the amount of fluid flowing out of the ground of the well is reduced or the passage is clogged exhaustion without separately re-perforating By utilizing the drilling holes, the existing closed fluid passages are opened to increase the flow rate to regenerate the wells, thereby reducing the cost of drilling due to additional drilling and the cost of relocating and re-installing larger facilities and equipment. Not only can it do, it has an excellent economic effect.

In addition, the present invention allows the explosive force acting horizontally at the position of the underground velocity existing when developing new boreholes of groundwater, hot spring water, natural gas and petroleum boreholes, repeated re-blasting, radial blasting Therefore, the effective range of the blasting effect in the ground can be expanded to maximize the success probability of drilling and drilling, that is, the opening probability.

In addition, the explosive emitter of the present invention is not only recyclable because it is formed of a metal body of high strength, but also enables several times of continuous construction, thereby enabling continuous construction at a doubled of the loading speed. There is no fear of explosion, half width, etc., and the handling is safe, which increases the safety of blasting.

In addition, the present invention is a technology that considers the environment, by minimizing the contamination of the underground environment through the drilling hole due to the perforation of the ground indiscriminately perforated ground for the extraction of groundwater, oil or gas mining, and also drilling and drilling Because it suppresses the overdose of the effect is contributing to environmental conservation.

As described above, the present invention applies the concentration principle of the explosive force by the explosive radiator manufactured to have the directionality, the concentration, and the persistence of the explosive force during the explosion to form horizontal holes in the underground and / or to expand the openings of the underground hollow walls. In addition, it is an excellent technology that increases the efficiency and economic efficiency of construction because it can be repeatedly exploded and repeatedly recycled with one loading.
