Description
The present invention relates generally to explosive.The present invention be more particularly directed to be fit to make the method and apparatus of flowable explosive, especially emulsion explosive.
When explosive was used in the civil blast operation, by blast hole drilling, with in bulk or assembling blasting explosives composition filling, then explosion came breaking up rock then.Plastic cement or emulsion explosive composition are used in many blasting operations.The water-in-oil latex blasting explosives composition contains oxygen-supplying component, the discontinuous phase of the drop of the oxidizer salt aqueous solution for example, and it is dispersed in the organic oil external phase in the presence of one or more emulsifying agents.The oxygen supply external phase that is dissolved in the emulsion explosive composition in the oil only contains small proportion water or only contains and adds water.Discontinuous phase can be an eutectic composition, in other words the eutectic point of the component salt of the fusing point of said composition or discontinuous phase or eutectic scope.The slurry explosives composition comprises a kind of oil-in-water latex.
Latex and slurry explosives composition contain not quick-fried explosive matrix, and it mainly is made up of latex or plastic cement.Having only when sneaking into sensitizing agent this matrix to become can be quick-fried.It can contain self-destruction material (for example trotyl or nitroglycerine) or porous material (for example glass microsphere, plastic microsphere, expanded polystyrene microballoon or gas foam.People know and use gas phase body sensitized emulsion explosive in the prior art, and this is usually with chemical reagent, sneak in the matrix as nitrate to reach.This chemical reagent decompose or with matrix in component reaction form gas foam.
In a large amount of bulk explosives parts of needs, the factory that is everlasting makes.Be transported to the explosion place or movably making on the spot in the producing apparatus on a small scale with truck.
After the manufacturing, blasting explosives composition must be loaded in the borehole.Some on-the-spot producing apparatuss comprise the bulk explosives composition for the holonomic system of advancing borehole.The filling borehole promptly injects mainly by three kinds of methods, pumps into or is blown into the filling industry and finish, and employed method depends on the type and convenient use of product.
The simplest form, filling includes only topples over the container that contains blasting explosives composition, just directly pours blasting explosives composition into borehole.Sometimes, use spiral propeller that blasting explosives composition is transported to heel from container, pour borehole into by gravity.On the contrary, being blown into filling uses a large amount of pressurized gass that blasting explosives composition is blown into borehole by delivery hose.Used the filling that is blown into of blasting explosives composition from the sixties, Australian Patent No.441775(Fox), 466558(Persson), 469494(Bizon and Simpson) and 474509(Hay and Fox) in narration is arranged.
Prevailing filling bulk explosives method for compositions can be to utilize machinery or pneumatics by delivery hose blasting explosives composition to be sent into borehole.It is desirable to blasting explosives composition has enough low viscosity, can pump into borehole at an easy rate from storage vessel.Viscosity is higher, needs the pump pressure of mobile blasting explosives composition higher, and the burden of starting pump is bigger.If viscosity is too high, pump can not produce enough power and come mobile blasting explosives composition and/or pump to begin to skid.On the contrary, if the emulsion explosive composition viscosity is too low, it is tending towards flowing into crack in the borehole and tomography and the underground water that loses or leached damages.
Find to make the plastic cement of sensitization or practical more and the effective means and the equipment of emulsion explosive at present.
According to the invention provides a kind of method of making the sensitization flowable explosive, the method comprising the steps of is:
Utilize an explosive matrix pump along the pipeline with mixing apparatus just or close on its dirty end non-blasting powders matrix pumped for source from it;
Simultaneously, by lubricant pump lubricating fluid is pumped from the lubricating fluid supply source along pipeline;
Simultaneously, utilize the pore forming material pump along one alone fluid hose enter pipeline, just or close on mixing apparatus upper reaches end and flowable pore forming material pumped into for source from it this explosive base is bubbled; With
In mixing device, explosive base and lubricating fluid are mixed together with pore forming material, form sensitizing explosive.
The example of the flowable explosive of described type is slurry explosives and the emulsion explosive that has plastic cement or latex base respectively, so, mix the plastic cement or the emulsion explosive that have caused sensitization, depend on the circumstances.
It is preferably approaching as far as possible or direct at the upper reaches of mixing device end position that pore forming material is pumped into pipeline.Especially, mixing device can pump into pipeline directly at the upper reaches of mixing device end position with pore forming material at the dirty end of pipeline.
Pore forming material can be a kind of chemical foaming solution, for example has the solution of solvent (comprising water) and solute (comprising nitrate ion).Usually adopt sodium nitrate solution, explosive base and/or lubricating fluid contain ammonium ion so that explosive causes that by forming nitrogen bubble therein chemistry bubbles and sensitization, it according to reaction formula be:
NH
+ 4+NO
- 2→2H
2O+N
2
Each pump can be reciprocating type positive-displacement pump, and these pumps can mutual connection, otherwise perhaps, synchronized with each otherly is transported to the coupling outlet exactly.In other words, the pump of explosive base is got, and the pump of lubricating fluid gets that get with the pump of pore forming material can be by means of reciprocating type positive-displacement pump, and they accurately are transported to the coupling outlet mutually synchronously.Just generally lubricating fluid is delivered to or send into the location point of pipeline in abutting connection with explosive base so that when they during by pipeline lubricating fluid form the ring-type lubricant layer on every side in explosive base.Particularly, explosive base and lubricating fluid can pump into pipeline in same position, and lubricating fluid and explosive base pump into pipeline, so that they make lubricating fluid around the explosive base core during simultaneously by pipeline, form the ring-type lubricant layer between core and pipeline.Lubricant can contain water and/or the suitable organic liquid as ethylene glycol, has suitable low viscous fuel for forming in final sensitization blasting powders; And it can contain ammonium ion.More particularly preferably be, lubricating fluid can be selected from water, ethylene glycol, glycol ether, their mixture or other suitable organic liquid.
Pipeline and stream pipe can comprise flexible hose, are fit to the delivery explosive and go into borehole, and pipeline generally comprises jet pipe in its lower end, and mixing device, and it is contained in the dirty end of jet pipe.Flexible pipe can be tied up or press together, so that they in use stretch side by side.
The important advantage of this method is, when using this method to enter borehole and discontinuous operation as the filling sensitizing explosive, has only mixing device and section of tubing (flexible pipe or jet pipe), if having, then at the dirty end of mixing device, need contain sensitizing explosive.Danger has reduced; And when needs are scrapped sensitive explosive, for example if any, be enough to make this sensitive explosive inadequacy through cycle long period, then only lose quite few explosive at discontinuous operation sensitive explosive.
A further advantage of the invention is the aerating ratio that can improve explosive base, and mix and under lower pressure, to carry out, and can control the aerating ratio of matrix quite exactly.Moreover, when adding gasoloid and do not make with lubricator, in venting solution, can adopt quite a spot of water.
Further, can provide manufacturing sensitizing explosive equipment according to the present invention, this equipment comprises:
An explosive matrix pump, it has one for the inlet of emulsion explosive matrix and the outlet of linking pipeline;

A lubricated liquid pump has a lubricating fluid inlet and an outlet that is connected on the pipeline,
It is identical or adjoin each other that explosive base pump and lubricated liquid pump, its outlet are connected position on the pipeline.
As mentioned above, the running that can interconnect of these pumps, or opposite run-in synchronism can be positive-displacement pumps.Especially, explosive base pump, lubricant pump and pore forming material pump can be positive-displacement pumps, their runnings that interconnects, and the phase mutually synchronization is used in the conveying of coupling outlet.
This equipment can comprise:
The inlet of this matrix pump is linked in an explosive base source;
The pore forming material pump intake is linked in a pore forming material source; With
A lubricant source is linked the lubricant pump inlet.

This engine can be an air engine, by air-operated drive, or hydraulic pressure or waterpower or driven by power, this framework is a guide rail form, has pair of slide and ground is engaged so that the operation of its erectility with framework.
By embodiment, consult description of drawings the present invention now:
Fig. 1 represents the sectional side elevation of apparatus of the present invention.
The orthographic plan of Fig. 2 presentation graphs 1 device.
In the drawings, numeral 10 is devices of the present invention.Device 10 can be portable by two people, and it comprises the supporting of metal pipe material 12 elongations, at its two ends a pair of carrying handle is arranged.Framework is a guide rail form, has pair of slide 15, can be along the ground push-and-pull with it.The latex matrix of container 16 is installed on the framework 12 for the source, and pore forming material is a container 18, and the lubricating fluid source is a container 20.Container 20 is omitted in Fig. 1 for clarity of illustration.
Reciprocating-piston and cylinder type positive-displacement pump are 22, and it has the inlet of a connection container 16, and one is equipped with back the only outlet of valve 24, links to each other with air engine 26 drive-types, and pump is all direct or non-to be directly installed on the framework 12.Be installed in both sides and lean against the continuous operation in its next door, so that synchronous operation simultaneously, pore forming material pump 28 and lubricated liquid pump 30 respectively have piston rod 32 and 34, and they are linked on the piston 40 of pump 22 by connecting rod 36 and 38 respectively.
Dirty end at flexible pipe 46 is equipped with a jet pipe (not shown), at its dirty end a rotary type or static pressure type mixing tank (also not illustrating) is arranged.Flexible pipe 46 is fed to jet pipe and mixing tank, and flexible pipe 50 is stretched over mixing tank along jet pipe is other, is fed to mixing tank, and mixing tank is fed at the vertical nozzle exit of jet pipe again.
During use, device 10 generally is placed on the explosion place, for example at underground mine.By means of handle 14 general two these devices of people's portability, flexible pipe 46 and the jet pipe that connects are coiled on the framework 12, and container 16,18,20 contains required composition.
Usually, use this device, make the body sensitized emulsion explosive of water-in-oil-type, this blasting explosive package oil scraper base external phase and the water base discontinuous phase that is dispersed in the external phase according to the inventive method.
In the type system, container 16 contains the latex base, and container 18 contains the SODIUMNITRATE foaming aqueous solution.Container 20 contains lubricating fluid, for example suitable water/ethylene glycol mixture, and it contains ammonium ion, foaming catalysts (as thiocarbamide) and PH control additive etc.
In the explosion place, with 26 while of engine driving pump 22,28 and 30.Pump 22 ends upper reaches end that valve 24 pump into flexible pipe 46 from container 16 by returning with the latex base; The lubricating fluid that pump 30 will receive from container 20 by flexible pipe 44 is by at the upper reaches of flexible pipe 46 end and directly pump into flexible pipe 46 in abutting connection with the flexible pipe 48 of valve 24.The latex base is along flexible pipe 46 streams, and its passage quilt along flexible pipe 46 is lubricated around the circular layer of its lubricating fluid, makes along flexible pipe 46 to be easy to move.Pump 28 receives foaming solution by flexible pipe 42 from container 18, and along flexible pipe 50 pumpings.Can consult aforementionedly about this point, foaming solution can contain part ethylene glycol, ethylene glycol in the foaming solution and lubricating fluid be mixable water and can make fuel, though can use other mixed water fuel to replace ethylene glycol.
At the dirty end of flexible pipe 46, flexible pipe 46 and flexible pipe 50 are fed to the mixer entrance in the jet pipe respectively, and here lubricating fluid, latex base and foaming solution mix all sidedly and equably, form emulsion explosive.
It should be noted that before they finally are combined into emulsion explosive, allow short mix between lubricating fluid and foaming solution, thus, nitrate ion in the permission foaming solution and the ammonium ion in the lubricating fluid fully react, so that form nitrogen bubble effectively reliably.
Should be specifically noted that in the variation of the inventive method, lubricating fluid can be introduced flexible pipe 46, or jet pipe, the end of upper reaches slightly of mixing tank.In the method, blended liquid rapidly, be lubricating fluid and the foaming solution uniform mixing that can have a chance or opportunity is in the same place, begin to bubble and ammonium ion is contacted with nitrate ion, lubricating fluid and foaming solution are emulsified into the latex base in mixing tank afterwards, thus, further promote the effectively reliable of emulsion explosive to bubble.
Should note in this point, by chemistry foaming sensitization water-in-oil latex explosive is problematic, when foaming solution is sneaked into the latex base that contains ammonium ion simply, the speed of reacting of bubbling depends on many chemical factors and other practical situation, for example pH value, temperature, time and catalyst concentration, but particularly, mixing efficiency is the determinative of foaming speed of response.This is because when being added to foaming solution in the water in oil emulsion matrix, the discontinuous drop of foaming solution can form in the oil-continuous phase of latex base.Ammonium ion generally is contained in the discontinuous aqueous phase of latex base in this case, is in contact with one another for making the nitrate ion in these ammonium ions and the foaming solution, and it is two-layer that ion-transfer need be passed latex oil phase/water.Because external phase is oil base, so water soluble ion diffusion transfer slower is decision speed.
The special advantage of the present invention is to eliminate the restriction of this decision speed, by ammonium ion being provided in lubricant solution and guaranteeing lubricant solution and foaming solution is in contact with one another, mix mutually to small part before this, or enter in the latex base mixes earlier than them at least.Because lubricating fluid and foaming solution mix easily in the aqueous solution, can make its short mix, promote nitrogen bubble and gasification effectively reliably, make drop separated from one another and produce the part short mix before separating ammonium and nitrate ion at least at the latex oil phase.Bubble the speed of reaction by temperature and chemical factor control, and ion diffusion control speed no longer.
Consider that above-mentioned viewpoint it should be noted that the effect of foaming solution and lubricating fluid can put upside down, in this sense, if desired, the solution that contains nitrate ion can be packed in the container 20 and be pumped by pump 30; The solution that contains ammonium ion can be packed in the container 18 and be pumped by pump 28.But the latter does not select for use usually, because the latex base generally contains ammonium ion, so that some foamings can take place along the whole length of flexible pipe 46, this is undesirable, because this can force the explosive of destroying in the flexible pipe 46 behind continuous breeching eye, and detonates before the next borehole of filling.But if the latex base does not contain ammonium ion, this effect of putting upside down is feasible, in this case, contains nitrate ion solution in fact with the super fatting agent solution effects, in fact will the foaming solution effects and contain ammonium ion solution.
