Description
Technical field
The present invention relates to the emulsion explosive that blasting operation is used.
Background technology
The main forms of the unusual explosion in colliery is: the coal ability often appears collapsing in permitted explosive for coal mine that ground quality is up to the standards and detonator in the actual explosion in down-hole reduces, stay residual medicine, detonation and unusual blasting phenomena such as miss-fire, investigation result shows it is because the powder charge passivation phenomenon causes, promptly the stress waves in soils that produces because of elder generation quick-fried big gun hole compresses in advance and adjoins time quick-fried blast hole projectile filling, make this blast hole projectile filling that induction detonation take place, detonation sensitivity reduces, even unusual blasting phenomena such as miss-fire, this stress waves in soils also may make the blasting cap initiation ability reduce or forfeiture simultaneously, or makes its generation drift time of ignition.Peril Incidents such as this phenomenon easily causes blown-out shot under the coal mine, stays undesirable root, powder stick detonation, blasting fume toxicity exceed standard, slungshot and gas and coal dust catch fire take place.
According to the data of having grasped, the discovery of unusual blasting phenomena (Explosives Malfunctioning) should originate from mid-term early 1980s in the colliery blasting operation, that early propose this problem is fritz Scholz, he has discussed mechanism and correlated phenomena that the explosive passivation causes to miss-fire in the article of delivering in 1981, but the Wieland M.S. in research centre, office Pittsburgh, U.S. Department of Interior mine professor has carried out research in depth in this field aspect many, thereafter, states such as Japan, France, Germany, Canada conduct a research in succession.(1986) paid close attention to the research of Wieland the earliest is that the firer of supply office of the former coal Department of Industry locates the Chen Zhengheng professor in China, thereafter, the technician of CCRI Blasting Technology Research Institute has carried out a series of research activities around this special topic, carry out some theoretical investigationes around water-bearing explosive bubble or space carrier and the explosive mechanical property concerns, bubble is subjected to the quick mechanism of pressure drop, emulsion explosive rheological characteristics, emulsion explosive impact sensitivity etc., obtained useful achievement.The achievement that obtains can be summarized and is summarized as follows:
(1) in the delay blasting of colliery, the powder charge passivation has four kinds of possibility mechanism in the adjacent big gun hole: the mutual compressive action of the infiltration of directly destroyed, the adjacent big gun of powder stick hole reactant gases, pipe effect and adjacent big gun hole stress waves in soils.Experimental study shows: the influence of first three kind or accessory, or possibility is very little, has only the mutual compressive action of adjacent big gun hole stress waves in soils, can the viewed phenomenon of reasonable dismissal.
(2) for improving the accuracy of experimental study, need realistic simulation to be subjected to the big gun hole wave-wave shape feature that meets with stresses, numerous investigators has designed various experimental installations, some device is by strict control dynamic condition, feasible simulation to the scene reaches comparatively perfect condition, and the relative error of waveform parameter is than being much smaller in the colliery under these simulated conditions.Utilize the testing apparatus that designs separately to carry out the typical industry explosive and adding the experimental study of depressing detonation property variation and Restoration, the conclusion that generally draws is dynamite not passivation substantially, the anti-pressure ability of emulsion explosive is higher than water gel explosive and powder ammonium nitrate explosive, but do not have restorability, and theoretical analysis produce the mechanism of this species diversity.
(3) investigated emulsion explosive pressurized inactivating performance and spacing [of holes and the relation of the time difference of detonating, conclusion is to cause that aspect the explosive pressurized passivation factor, spacing [of holes occupies essential factor.Further conclusion shows that when spacing [of holes was 45cm, the frequency of miss-firing was about 50%; When spacing [of holes was 60cm, the frequency of miss-firing will reduce a lot.Therefore United States Bureau of Mines forbids that spacing [of holes is less than 60cm.But different with explosive property because of performances of rock, investigator's field experiment conclusion is not entirely similarly or identical.
(4), coal mining explosive pressurized PASSIVATION MECHANISM is described, but special emphasis concentrates on bubble and the changing conditions of space carrier under pressure in the system by experimental study and theoretic discussion.
Above-mentioned achievement in research has been started the research field of the unusual explosion in colliery undoubtedly, haves laid a good foundation for preventing the unusual explosion in colliery.But also there is following limitation in research work, and it is restricted the directive function that China's coal-mine safety in production has practical significance:
(1) the unusual blasting phenomena of China's coal-mine lacks system investigation and analysis, its seriousness and feature difficulty is done estimation and judgement, thereby can't accomplish conscious prevention.
(2) permitted explosive for coal mine, allowed for use in coal mines delay electric detonator pressurized PASSIVATION MECHANISM also do not have comprehensive and accurate explanation.
(3) the mining explosive of pressure resistant type, the especially development of pressure resistant type emulsion explosive for coal mine also need effective and feasible technological approaches.

This pressure resistant type preparation of emulsifying explosive is three grades of emulsion explosive for coal mine.
Campaign and pressurized PASSIVATION MECHANISM by the passivation of emulsion explosive pressurized are analyzed, substantially, definite: in the emulsion explosive system, the stable of emulsion structures and sensitization bubble is the key factor that influences the passivation of emulsion explosive pressurized, and to keep the emulsion structures of emulsion explosive and sensitization bubble stable, the formation of tough interfacial film and to have flexible bubble be important.Discover that the crystalline growth rule of emulsion explosive shows that its crystalline growth is subjected to the strong restriction of interfacial film.If interfacial film thickness and density are enough big, will effectively check the break rate of expansion of hole of interfacial film.Therefore, increase the concentration of emulsifying agent or the function of emulsifying agent, especially can form the emulsifying agent of microemulsion, will make every performance generation qualitative leap of emulsion explosive, especially significant to forming good resistance to pressure.Therefore this will become the main principle that pressure resistant type emulsion explosive development technological approaches is selected.
About determining of emulsifier content and kind, clear and definite, from the emulsion structures angle, the resistance to pressure of emulsion explosive depends in the system oil phase that to have the interfacial film densification of emulsifying agent more than needed and system tough, therefore, the selection of emulsifying agent and combination are just most important.Under the constant situation of molecular length, fill factor is big more, and required dispersity is high more; Also show simultaneously, the macromolecule emulsifier that molecular length is bigger, can not form the emulsion system of the typical milk sap feature of having of high dispersing, it mainly is dispersed in water in the oil phase with absorption swollen form with hydrophilic radical, unordered dispersive macromole forms irregular network in system, reflect stronger gel property.Therefore, emulsifying agent is selected to take into account particle dispersity and interfacial film intensity.
For this reason, adopt following dual mode to determine emulsifying agent.The one, the Span-80 emulsifying agent of the targeted modification of employing.The modification Span-80 emulsifying agent of selecting for use is to introduce certain flexible long chain alkyl group is arranged in this molecule of department, when the emulsifying agent molecular orientation closely is arranged in phase interface, long chain alkyl group can bending be stretched to oil phase, so just, can between two oleic acid moleculars, play the effect of barrier, thereby the compactness extent of interfacial film is increased, and simultaneously, the nitrogen-atoms in the molecule also can form hydrogen bond with water molecules, thereby make interfacial film strengthen, cause stabilization obviously to strengthen the resident effect of water molecules.The 2nd, the compound synergy of employing emulsifying agent.Studies show that the compound of emulsifying agent nearly all can cause the intermolecular repulsive interaction of emulsifying agent to reduce, and makes molecular arrangement tightr, increases the compactness of interfacial film.Analyze the mechanism of action of macromolecule emulsifier, the long chain hydrocarbon groups in its molecule is to keep the stable key point of milk sap.Because this macromolecular chain segment of freely unfolding in oil film is adsorbed on small-molecule substance in the oil phase around self firmly just, spread over the appearance of disperse phase particulate, constitute the tough and tensile oil film of successive.And it not only is adsorbed on a microparticle surfaces, also may be adsorbed on two or several microparticle surfaces, make between the disperse phase particulate not only between across the oil film of sealing but also be subjected to the constraint of chain alkyl, promptly macromolecule emulsifier has three-dimensional provide protection to milk sap.But, the also existence of this long chain alkyl group just, the time spent of doing that makes emulsion liquid tie up to be subjected to shearing external force, because of it has comparatively firm steric conformation flexible not enough, very easily destroy the structure of system similar gels and breakdown of emulsion occurs, this makes the application of macromolecule emulsifier in continuous emulsifying explosive production technology be restricted.Obviously, there is not long segment and have the emulsifying agent of certain three-dimensional arrangement to be only rational selection.
Based on above-mentioned analysis,, best with Span-80 emulsifying agent and PCE composite effect by M201, soybean lecithin, TX-03, PCE etc. and modification Span-80 emulsifying agent composite testing.
About the selection of bubble sensitization mode because no matter the inflexible bubble carrier still all easily break under stress wave activity under mechanical effect, and be changed to irreversible, so chemical foaming sensitization mode is the selection of the best.
For satisfying the resistance to compression requirement, the homogeneity that is distributed in the sensitization bubble in the system also is vital, therefore also following special consideration should be arranged for the foaming mode:
(1) whipping agent super-fine processing.Facts have proved that for many years the foaming of H organic blowing agent is large-minded, bubble is trickle, even, but the H organic blowing agent is water insoluble.After deliberation, adopt ultra-fine 180～200 order H whipping agents, use separately or with the compound use of inorganic foaming agent, can both obtain effect preferably, in a kind of solution based on water, foaming agent consumption is generally 0.1%～0.2% with its uniform mixing.
(2) whipping agent mother liquor preparation.For making foam even, whipping agent can not once add, and must be continuously to add, therefore must preparation convenient carry and can with the mixed uniformly whipping agent mother liquor of matrix.Can adopt two kinds of methods: the one, foaming agent water solution is carried out emulsification, the whipping agent after the emulsification is transported in the sensitization machine mixes sensitization with latex matter; Another kind is to add tensio-active agent, jelling agent in foaming agent water solution, whipping agent and mother liquor have prevented the precipitation of whipping agent solid particulate on the one hand like this, also easily and the matrix uniform mixing, two kinds of methods can reach the operational throughput of whipping agent and the requirement of foaming sensitizing on the other hand.
(3) foaming sensitizing speed determines.At present, emulsion explosive production generally all adopts fully continuous line, and the chemical foaming sensitization time is to decide according to the practical situation of continuous sensitization machine and automatic medicine-filling machine in producing.If but the whipping agent decomposition is too fast, the gas of generation is difficult for forming bubble or forms than air pocket, influences product performance on the contrary; If the sensitization foamed time is slow excessively, influence powder charge, packing, warehouse-in again.What and concentration adjustment just of consumption by whipping agent and different accelerator levels, reach the control foamed time, both satisfied the needs of full-automatic charge machine, satisfied the requirement of semi-automatic charge machine again, the requirement that reaches full continuous production and improve the product compressive property.
Theoretical and test shows, adopts compound emulsifying agent, increase emulsifier content, the sensitization of employing chemical foaming agent etc. all can improve the withstand voltage properties of emulsion explosive.A, B, C, D, the E sample series of design in this test adopt the widest emulsion explosive for coal mine of China's consumption as basic components, adjust its content, add the auxiliary agent that strengthens interfacial film intensity according to the milk sap stable theory, contrast its sensitization mode.According to this experimental study, the voltage endurance capability of each prescription is listed in table 1.
By table 1 as seen, the critical passivation of C sample series is apart from minimum, and this sample adopts Span-80 and petroleum by-product, macromolecular material compound, make compound emulsifying agent, emulsifier content be 2.0%～2.7% o'clock for its critical annealing point, therefore, adopt the basic components of C sample as the pressure resistant type emulsion explosive; Because emulsifier content is more than 2.7%, its critical passivation distance no longer changes, and indicates that its emulsifier content further strengthens the voltage endurance capability that no longer can improve system, at this moment, the actual passivation of product distance is 2cm, less than critical passivation apart from more than two times of 7cm.
Carry out aspect the emulsion explosive withstand voltage properties special setting simultaneously because the increase of emulsifier content, the oxygen balance of whole system will depart from ideal value, should give adjustment again this moment with the mathematical model of industrial explosive formulating of recipe.After the prescription typing, make factory's amplification productions such as limited liability company through long wide civil explosive material, by explosive product quality inspection center, the coal-mining industry Huaibei product performance are tested, inspecting standard is GB18095-2000, the every performance index detected result of pressure resistant type preparation of emulsifying explosive sees Table 2, and nature examination storage period the results are shown in Table 3.By table 2 as seen, a series of indexs of pressure resistant type emulsion explosive have have all met or exceeded the GB18095-2000 requirement.The preparation method of emulsion explosive and the production technique of existing emulsion explosive are basic identical, do not elaborate here, and preparation process condition sees Table 4.
Useful technique effect of the present invention is embodied in following aspect:
1, uses pressure resistant type emulsion explosive of the present invention, can be implemented under the prerequisite that keeps existing mining explosive mass conservation, reach the purpose of the unusual Blasting Control ability in effective enhancing colliery.
2, the blast performance of pressure resistant type emulsion explosive of the present invention meets the GB18095-2000 standard, and its emulsion explosive for coal mine compressive property is more than 1.5 times of its pressurized passivation threshold value.
