Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

The present invention relates to cartridges and related loading systems, and more particularly to loading hardwood holes for the purpose of breaking hardwood.

[0002]

[Prior art]

One known method of crushing or drilling hardwood, such as rock, is by drilling and blasting. The method involves drilling a hole in the hardwood and loading the hole with a large amount of explosive, preferably some type of filler. In its most basic form, the method places a certain amount of explosive agent at the bottom of the hole, fills the rest of the hole with filler, such as excavation material or aggregates, and breaks the hard material into holes. Includes detonating an explosive that raises atmospheric pressure at the bottom. In this method, a large amount of the filler material often jumps out of the hole.

[0003] Usually, explosives are supplied as bulk bulk material or packaged as cartridges. Cartridge systems are commonly used for small charge blasts and have detonators. The filler is usually used as a bulk material in bulk, but can be filled into a package. Explosives and fillers are purchased, transported, stored and used separately. Similarly, both are separately loaded into the holes by separate equipment.

[0004] For commercial reasons, it is important that hardwood crushing occur as quickly as possible, whether mining or civil engineering. Additional commercial benefits can be obtained if holes are loaded with minimal material handling and use of low cost equipment. For security reasons,
It is desirable that no filling material pops out of the hole, or at least only a minimum of filling material pops out of the hole at a low speed.

FIG. 1 shows a cartridge of the simplest embodiment and an associated loading system. The cartridge 10 includes a first compartment 12 containing a filling material 14 such as gravel, and a second compartment 16 containing an explosive 18.
The filler acts to absorb the blast energy and to turn or deflect. The term "energetic material" means an explosive, a propellant, or a combination thereof. The filling cartridge 10 in its most basic form comprises a cylindrical shell 20 having on the opposite side an inner partition 22 forming first and second compartments 12 and 16. A detonator 28 for detonating the explosive 18 is provided in the second compartment 16. In the present embodiment, the detonator 28 is activated by an electromagnetic wave.

In use, the cartridge 10 is placed at the tip of a hole formed in the hard material to be crushed, with the second compartment first or below. When the cartridge 10 has the tip of the hole (
If it does not fall to the bottom), it may be pushed down to the bottom by the use of a general loading rod of the same cross section. The connection between the loading cartridge 10 and the loading rod constitutes a loading system for loading holes in hardwood. In the present system, the lower end of the loading rod is connected to the open end of the first component (ie, the upper end of the cartridge 10), as will be described in detail with reference to FIGS. This is easily done by connecting the end faces.

FIG. 2 shows a cartridge 10 A according to a second embodiment and a loading system 30 related to the cartridge 10 A. In the cartridge 10A, the projecting portion 32 of the shell 20 has the wall 2
It is essentially the same as the cartridge 10 shown in FIG. The recess 34 receives the lower end 36 of the loading rod 38. The junction between the recesses 34 and 36 is tight so that the cartridge 10 is naturally supported by the loading rod 38. The loading rod 38 and the cartridge 10A are connected to form a loading system 30. The loading rod 38 is provided with a vertically extending slot, recess or groove 40 through which the firing cord 42 passes. The cord 42 has one end connected to the detonator 28 and the other end connected to a detonator (not shown).

In the present embodiment, the lower end 36 of the loading rod is received in the recess 34, and the cartridge 10 A is pressed against the loading rod 38 in a state of being in contact with the wall 24. The connection between the loading rod 38 and the cartridge 10A is inserted into the hole of the rock 46 (or the hard material to be crushed). As shown in FIG. 1 and FIG.
Are formed from a single shell 20. Regardless, the thickness of the wall of the shell 20 that forms the first compartment 12 may be formed to be thicker than that of the second compartment 16. As a result, a downward pressing force is applied to the loading rod contacting the end wall 24, and a compression force is applied, whereby the diameter of the first compartment 12 can be increased. As the diameter of the first compartment 12 is increased, the sealing of the hole 44 is increased, and thereby the blasting effect is improved. This is also
The filler 14 allows the blasting energy to be redirected or redirected away from the filler rod to the wall of the hole 44.

FIGS. 3 to 10 show a cartridge 10 B and a loading system 30 B according to a third embodiment. Here, the first compartment 12 of the cartridge 10B is constituted by a first container 48 containing the energy absorbing charge 14, and the second compartment 16 is constituted by a second container 50 containing the explosive. Container 4
8 and 50 are connected end by end. This connection is a connection in the form of an internal recess 52 in the lower end 54 of the first container 48 and the upper end 5 of the second container 50.
This is achieved by providing a connecting portion that connects to the connecting portion provided in the form of a projection on the projection 8.

As shown in FIG. 3, the first and second containers 48 and 50 are removably connected to each other by pressing the protruding portion 50 against the concave portion 52 to form the cartridge 10 B. In use, the cartridge 10B is lowered into the hole 44 formed in the hard material such as the drift rock or the rock 46 with the second container 50 being the first or the lowest.
As a result, the hole 44 is loaded with the filler 14 and the explosive 18.

The first container 48 is in the form of a cylindrical tube having a conical inner wall 60 near its upper end 62. The conical wall 60 starts from a position below the upper end portion 62 and goes to a point on the second container 50 side. Extending vertically inside the cylindrical body of the first container 48 is an internal passage 64. The passage starts at the upper end 64 of the first container 48 and extends toward its lowest point 66 above the lower end 54. The passage 64 extends through the conical wall 60. The conical wall 60 is a container 48
Of the cartridges 10 and 1 shown in FIGS.
It is regarded as equivalent to the end wall 24 of 0A. This is that the conical wall 60 can be considered as one of various forms of the wall of the first compartment 12. Lower end 54
A disk-shaped closing plate 68 is provided to close the plate. The plate 68 is formed by an arcuate blocking member 70 that abuts the passage 64. One or more inner lands 72 may be provided or provided on the inner surface of container 48 slightly above lowest point 66 to secure plate 68.

In the process of forming the cartridge 10 B, the first container 48 is first turned in the opposite direction, and the filler 14 is loaded from the lower end 52. The end plate 68 is inserted into the lower end 52, and is locked to the land 72 with the blocking member 70 covering the end of the passage 64.
The end plates 42 are glued, welded or otherwise secured.

The second container 50 also has an integral end wall 74 extending across its upper end 58.
In the form of a short cylindrical tube with The protrusion 56 is formed by forming a shoulder 76 in the circumferential direction at a position around the container 50 and below the upper end 58 thereof. The end wall 74 is provided with a hole 78 communicating with the second compartment 16. The lower end 80 of the second container 50 is closed by an end wall in the form of a disk 82 abutted, glued, welded or otherwise secured to the inside of the lower end 54. However, before the end wall 82 is fixed, the second container 50 is filled with the explosive 18. In addition, the detonator 28 is inserted into the container 50.

The end plate 68 and the projection 56 can be used separately or in combination to function as a bulkhead close to the wall 22 separating the filler 14 and the explosive 18 of the cartridges 10, 10 A of FIGS.

In the present embodiment, the detonating device 28 is of a type that is physically connected to the detonating source via a cord 42 or a lead 42. The cord or lead 42 has a hole 7 in the projection 56.
Passing 8 Further, when connecting the first and second containers 48 and 50, the lead 42 passes through a passage 64 extending from the lower end 54 of the first container 48 to the upper end 62.

As shown in FIG. 3, the associated loading system 30 B supplements the conical wall 60 and
An extended filling bar 38 having a conical and tapered lower end 36B is provided for locking inside the upper end 62 of the container 48. As a result, the cartridge 10B is
8 may be physically supported by the lower end 36B. Therefore, if necessary or convenient, the cartridge 10B is simply pressed against the filling rod 38, and the filling rod is inserted into the hole 44,
As a result, the explosive 18 is loaded into the hole at the same time, and the filler 14 and the filler rod 38 themselves are loaded into the hole. In order to connect the detonator 28 to the detonation source, a cord 42
A vertically extending slot 40 is provided. A series of vertically extending pins 84 (see FIG. 10) are pierced through the bar 38 across the slots 40 to retain the cord 42 within the bar 38.

In use, the filler bar 38 may be secured by supporting or pressing the top end thereof with heavy equipment such as a jumbo, excavator bucket or bulldozer bucket, or other device means such as a wedge or jack. Further, by using the above-mentioned heavy equipment to expand the diameter of the first container 48 and bring the first container 48 into contact with the side wall of the hole 44, a compressive force can be applied to the first container 48 by the filling rod 38. To assist in expanding,
The cartridge 10B (or the cartridge 10, 10A) may be formed with a vertical weak line. Pre-loading the cartridge 10B to effectively radiate the filler as described above assists in redirecting or deflecting blast energy away from the filler rod and into the filler itself, and reducing bounce. .

In embodiments where the detonator 28 is activated via electromagnetic / magnetic or electromagnetic / magnetic fields, an electromagnetic transmitter is located at or near the lower end of the filler rod 38. In addition, to aid in the propagation of electromagnetic / magnetic waves or electromagnetic / magnetic fields, the filler 14 may be formed of a material that propagates such fields or waves, or the filler 14 may generate electromagnetic or magnetic waves, electromagnetic or magnetic fields. Propagating particles can be doped.

In a further variation, an additional container similar to the second container 50 (hereinafter a third container) may be supplied with explosives only to function as a booster cartridge. The booster cartridge is detachably attached to the lower end portion 80 of the second container 50. This is achieved in the same manner as when the second container 50 is made detachable from the first container 48. Alternatively, one or more booster cartridges are initially placed in holes 44 and pushed to the bottom by inserting cartridges 10B and / or filler rods 38 into the holes.

In addition, the cartridges 10, 10 A, 1
Because the ends are sequentially connected to the upper end of OB, an additional separate container or cartridge for containing the filling material may be provided. These additional containers or cartridges may be configured to be detachable end to end.

FIG. 11 shows a further embodiment of a cartridge 10 C. Cartridge 10C
Is a first container 48 constituting the first compartment 12 for containing the filling material 16
And a second container 5 forming a second compartment 16 containing an explosive 18
0. The partition 22 between the first and second compartments is
8 in the form of a plug having an axial hole through which the eight leads 42 pass. The detonator 28 is installed in the second container 50. The open end of the second container 50 is closed by a wall 26 in the form of a plug. The other end of the cartridge 10C is closed by the end wall 24 through which the lead 42 passes. To enhance the sealing / closing effect, the first compartment 12, or container 48, is configured to be deformable when pressure is applied to the end wall 24 of the cartridge 10C within the hole. Such pressure is applied by a tamping or stuffing operation using a rod. The pressure causes the compartment 12 to expand toward the wall of the hole. This provides a sufficient holding force to hold the cartridge 10C in the hole without popping out at the time of explosion and without requiring an external device such as a filling rod. At this time, the cartridge 10C functions as a self-filling cartridge. This effect is most clearly confirmed for small holes of 18 mm or less.

A weak line or slit may be formed around the compartment 12 to promote deformation when a compressive force is applied to the end wall 24 and improve blast performance. Deformation and explosion may be further facilitated by molding the compartment 12 / container 48 with a deformable material such as thin-walled plastic or paper.

The first compartment 16 / container 50 is a tamped or cartridge 10C
Is in the form of a tube with an open end molded from a hard material capable of resisting deformation during the application of compressive force to the end 24. For example, compartment 16 may be molded from a rigid plastic, metal, or composite. The compartment 16 / container 50 is rigid and relatively strong to increase the rate of pressure rise of the ignited explosive 18.
This is advantageous because a sudden pressure rise causes a rapid complete combustion reaction of the explosive 18. The faster this reaction, the less variability in gas leakage prior to rock or other hardwood breaking or crushing operations.

FIG. 12 shows a further embodiment of a cartridge 10 D. Cartridge 10D
Differs from the cartridge 10C only in the shape of the partition wall 22 between the first compartment 12 and the second compartment 16. In the present embodiment, the partition 22 is formed integrally with the end 58 of the second container 50. In other respects, the cartridge 10D is the same as the cartridge 10C shown in FIG.

FIG. 13 shows an insertion cap 8 attached to the open end of the first compartment 12.
11 shows a cartridge 10E of a further embodiment which is the same as the cartridge 10C of FIG. In use, the insertion cap 86 functions to fit between the outer peripheral surface of the cartridge 10E and the side wall of the hole. As a result, two effects are obtained. First, it helps seal the holes. It also helps to hold the cartridge 10E in the hole during and after the blast so that the self-filling effect of the cartridge 10E is improved. The cap 86 has a central hole through which the lead wire 42 passes. The wall or skirt 88 is tapered to increase in thickness away from the second compartment 16. When the cartridge 10E is inserted into the hole, pressure is applied to the cartridge 10E through the cap 86. This presses the cap 86 against the open end of the compartment 12, and the taper of the skirt 88 causes the skirt 88 to stretch outwardly in the radial direction. The flaring of the skirt 88 may include one or more vertical slots or castellations in the skirt 88.
Is promoted.

FIG. 14 shows a further embodiment of a cartridge 10 F. Cartridge 10F
Differs from the cartridge 10E shown in FIG. 3 only in that the flat end wall is replaced by a truncated cone cap 24F. The cap 24F includes a truncated cone upper portion 90 whose diameter decreases in a direction away from the first compartment 12. The end portion 92 of the truncated cone 90 is provided with a hole through which the lead 42 extends. The other end of the cap 24F is provided with a short, substantially constant diameter projection 94 which is fitted or fixed to the inside of the upper end 62 of the first compartment 12. The cap 24F is associated with the raised cap 86 to help fit and secure the cap 86 to the inner surface of the hole into which the cartridge 10F is inserted.

FIG. 15 shows a further embodiment of a cartridge 10 G. In the present embodiment, a first compartment 12 containing an energy absorbing filler 14 and a second compartment 16 containing an explosive 18 are provided. Further, the cartridge 10G includes an end cap 24F and an insertion cap 86 similar to that of the cartridge 10F shown in FIG. The first compartment 12 is constituted by a first container 48, and the second compartment is constituted by a second container 50. However, the cartridge 10G differs from the cartridge 10F in the following points. That is, the lower end 54 of the container 50 does not use a separate end wall or plug, but
Is closed by forming an integral lower end. The partition wall 22 is in the form of a conical body 96 that forms a part of a connecting means 98 that connects the first container 48 and the second container 50. The connecting means 98 can be considered as a short tube with the cone 96 inside. The cone 96 is oriented so as to decrease in diameter from the first compartment to the second compartment. The top of cone 96 has lead 4
The hole through which 2 passes is formed. A side flange or ring 100 is formed near the bottom of the cone 96 outside the coupling means 98. Flange 100 abuts adjacent ends of first and second compartments 48,50.

The connecting means 98 may be composed of a plurality of separate connecting members, such as a cone 96 and a flange 100 as one piece, and two short tubes which are collinearly attached to both ends of the flange 100. However, it will be molded from plastic material. The coupling means 98 plays many roles. That is, explosive 18
Acts as a pressure partition during the combustion of During the burning of the explosive 18, the flange 10
0 is expanded so as to be in close contact with the side wall of the hole and to suppress the leakage of the high-pressure gas from the hole. Further, the filling material 14 in the area of the cone 96 is pushed upwards into the container 48, thereby radially compressing the filling material 14 against the inner surface of the first compartment 12 and then against the side wall of the hole. Reduces the further possibility of gas leakage. The detonator 28 is held at the center. Further, it protects the detonator 28 and the explosive 18 from moisture and other contaminants that may be present in the filler 14. Then, the first and second compartments 12 and 16 are held.

The cartridge 10 may be molded in various sizes, ie, diameters. As described above, the cartridges 10C to 10G have a characteristic of being able to self-fill in a hole, particularly when used in a hole having a small diameter of, for example, 18 mm or less. The cartridge 10 is suitable for a small drill such as a HILTI or KANGO hammer, or a contractor using a pneumatic hammer type drill as a main drill device. It can be appreciated that the manual drill described above is a standard device for all explosives handlers, and that no additional expense is required when using the cartridge 10. However, larger diameter cartridges may be used to crush or destroy rocks and other hard materials for the purpose of drilling larger diameter holes using track mounted drills, jack leg drills or jumbo mounted drills. it can. For example, since all the normally required components such as the explosive 16, the filler 18 and the detonator 20 are provided, the use of the cartridge 10 can simplify the blast and further increase the explosion speed. Therefore, there is no need to prepare spare explosives, fillers, and ignition devices and separately insert them into the holes.

While embodiments of the present invention have been described in detail, various modifications and variations will be apparent to those skilled in the art without departing from the underlying inventive concepts. For example, although the filler 14 is mainly described as a granular form such as an aggregate, other fillers, for example, a liquid or slurry-like material having physical properties such as adhesiveness with shearing force may be used. Furthermore,
Although the upper end wall of the cartridge 10, 10A has been shown as a flat wall 24 or a conical wall 60, a concave or convex curved wall that can engage or combine with other shapes, such as the complementary lower end of a filler rod. May be formed. Also, the first
And the components of the cartridge 10, 10G that define the extent of the second compartment need not be made of the same material. The second compartment containing the explosive is desirably of a suitable hardness to keep the explosive closed during the initial stages of detonation. On the other hand, it is desirable that the first compartment containing the filling material is relatively easily deformable in the radial direction and can be pushed against the side wall of the hole in order to enhance the blocking effect.

All such modifications and variations due to other configurations obvious to those skilled in the art are deemed to be within the scope of the invention, the nature of which is determined from the foregoing description and the appended claims.
