Abstract
A water-in-oil emulsion explosive characterized by containing an ethylene vinyl acetate copolymer. It has excellent long-term stability. Even when stored under a load for as long as about one year, the explosive is less apt to suffer a decrease in explosive performance and coagulates only slightly in such a degree that it comes to have weakly coherent partial coagulates which can be easily disaggregated. Even after long-term storage, charging with the explosive can be easily conducted with a charger. Since the explosive has excellent water resistance, it is suitable also for blasting in a water hole.
Description
Technical field
The present invention relates to a kind of explosive.In particular to employed oil-in-water emulsify explosive in the blasting operation of industries such as a kind of tunnelling, quarrying, mining usefulness.
Background technology
With what explosive generally was widely known by the people Nabit, water-bearing explosive, ammoniumnitrate explosives, ammonium nitrate-fuel oil mixture (hereinafter referred to as the ANFO explosive) etc. are arranged as employed industries such as blasting operations.In the middle of these explosives, water-bearing explosive is compared comparison safety owing to do not contain powder composition in its constituent with traditional Nabit, so be widely used in explosive in industry.Water-bearing explosive can be divided into slurry explosive and emulsion explosive two big classes, and wherein emulsion explosive is characterised in that and has plasticity and weathering resistance preferably.Emulsion explosive as the oil-in-water emulsify explosive at United States Patent (USP) the 3rd, 161, in No. 551 open since, carried out various improvement, now have better performance than original explosive aspect water tolerance, the security.
On the other hand, at the explosion scene, from the easy of the charging of explosive and the angle of the security when guaranteeing that explosive is handled, more and more to the mechanize outstanding request of explosive loading operation.Load operation for the machinery that carries out explosive, employed explosive need have higher security, and the ANFO explosive is carried out method that machinery loads in practical applications such as mine, stone quarry by shovel loader etc.But the ANFO explosive is compared with the oil-in-water emulsify explosive, because the ratio of components of the entrap bubble after the explosion is more abominable, so competent gas barrier need be set.In addition, when having moisture in the shothole, the blasting performance that can't obtain to be scheduled to because the ANFO explosive is dissolved in water, it uses the difficulty that also becomes.Therefore need to carry out following numerous and diverse operation sometimes: having the shothole of water, place, water burst hole, discharge the water in the shothole in advance, after insertions such as multitube, the ANFO explosive of in this multitube, packing into.In addition about the oil-in-water emulsify explosive, abroad, put down in writing in " about the research report book of effective tunneling technique " of the distribution of for example Japanese tunneling technique association, the oil-in-water emulsify explosive that has occurred being called bulk emulsifying explosive in actual applications directly is filled into the method for the bulk explosives system of shothole automatically by using air operated list pump etc.But this bulk explosives system is owing to use full-bodied oil-in-water emulsify explosive, and the removal treatment after its charging finishes and the management of residual explosive are more numerous and diverse, can cause the raising of cost.In addition, in the filling of bulk explosives,, also need expensive filling machine in order to ensure security.
Therefore, even the explosive that the shothole that has more moisture content is also spendable, security is higher that need can load as the fairly simple machine of air loading machine just.In order to overcome the above problems, open flat 7-223888 number, spy for example spy and open flat 11-278975 number etc. in the communique and put down in writing corresponding solution, put down in writing the progress of the development research of particle or granulous oil-in-water emulsify explosive.
But the particle of the oil-in-water emulsify explosive of putting down in writing in the above-mentioned communique or the method for spheroidizing are a kind ofly to make inorganic oxidizer aqueous solution crystallization in the emulsion, will carry out the method for spheroidizing behind the structure destruction of emulsion.
But well-known, in the ordinary course of things, behind oil-in-water emulsify explosive oxidizer aqueous solution crystallization, emulsion partly begins disintegration from its crystallization, so can't keep its sensitivity and performance as explosive.The explosive of this use form if adopt field mix mode or close with it mode, has only so very short time of a few hours to a couple of days, so can not cause very big problem till explosive is fabricated onto use.But explosive all can experience the several months usually from being fabricated onto use, and the time is than needing sometimes to experience about six months to 1 year under the long situation.Therefore,, also need it, and the experience several months also keep stable when above not with the aqueous oxidizing agent solution crystallization for particle or granulous oil-in-water emulsify explosive.Particularly load, also require the performance shape of oil-in-water emulsify explosive to keep stable, do not change for a long time for the machinery of tackling explosive.
In addition, be configured as the granulous explosive in long-time storage, under the situation of bearing a heavy burden when perhaps loading by machinery, produce explosive sometimes and condense, not disintegration of explosive during use is not easy to use.Therefore for granulous oil-in-water emulsify explosive, require it under Long-term Storage, the situation of bearing a heavy burden when loading, even explosive is noncondensing or condense and also be easy to disintegration by machinery.
