Abstract
A non-incendive, water-in-oil emulsion explosive composition is disclosed for use as P-5 permitted explosives in inter alia underyround coal mines. The explosive comprises from 50-80% by weight of an a aqueous solution of inorganic oxidiser salts, from 3-60% by weight of fuel phase and from 5-50% by weight of one or more solid dopants.
Description
The present invention relates in the underground coal mine of III degree inflation, to can be used as the oil-in-water emulsify blasting explosives composition of the explosive that P-5 allows.
More particularly, the present invention relates to nonflammable, oil-in-water emulsify blasting explosives composition and prepare the method for said composition.
P-5 type explosive is generally used for the underground coal mine of hyperinflation.These explosives are also through the special solid explosion that confirms to be applied in I degree and the II degree mine.Use NG type explosive at present.Yet these conventional explosives have some inherent shortcomings.These shortcomings comprise high poison gas and the detonation feature of physiological effect and blast back of using the NG explosive.
In the trial that overcomes more above mentioned shortcomings, use water gel to obtain limited achievement.Water gel demonstrates poison gas after the blast that has reduced and low detonation tendency.Yet the performance of this hydrogel is normally insecure.
The P-5 emulsion explosive is expected to overcome these problems, and the advantage of poison gas after the very low blast is provided simultaneously.They also are non-detonating.
The design of P-5 explosive itself is a kind of skill, because the relevant requirements of rules approval and performance is conflicted.In order to use a large amount of inert substance doping explosives by strict tunnel experiment.Yet, with inert substance doping explosive often to the susceptibility of explosive with and performance have a negative impact.Therefore, when carrying out this type of test, must reach best balance.
The oil-in-water emulsify explosive that can be used for P1 and P3 condition, for example I degree and II degree inflation mine is disclosed in the prior art.These explosives need refrigerant, because the explosion gas of the heat that discharges will certainly be lighted the gaseous mixture of the methane/air in the underground mine.This type of refrigerant is water and salt normally.US P 5017251 has illustrated the application of salt in P1 type explosive.
Similar prior art document has also been reported very high doping salt and has been used glass microsphere (the glass microballons of high capacity, GMBs) susceptibility (patent No.: the ZA 043516 to reach expectation, US 6017261M, AU 0067072M, AU 8656181, US 4976793M, CN1031363).The GMB that uses high capacity like this is infeasible economically suggestion.
Therefore, basic purpose of the present invention provides the P-5 emulsion explosive of the shortcoming and defect that overcomes prior art compositions.
The clearer and more definite purpose of the present invention provides (chemicallygassed) explosive P-5 oil-in-water type composition of the chemical aeration of viable commercial.
Further aim of the present invention provides the P-5 composition, wherein except utilizing water and an alkali metal salt as refrigerant, has clearly established the needs to the flame quencher.
Another object of the present invention provides the P-5 emulsion explosive composition, and when using when approval is used for the commercially available detonator of underground coal mine, said composition is responsive to ignition in the diameter of 32mm.
So, the invention provides nonflammable, oil-in-water emulsify blasting explosives composition, it comprises the aqueous solution of for example inorganic oxidant salt described here of 50-80% (weight), the fuel phase of 3-60% (weight) and such solid dopants one or more for example described here of 5-50% (weight).
Inorganic oxidant salt (it constitutes the discontinuous phase of P-5 emulsion explosive composition of the present invention in the aqueous solution) is selected from ammonium nitrate, base metal nitrate such as SODIUMNITRATE or saltpetre.And, can comprise the perchlorate of chemical sensitizer such as sodium, potassium or ammonium, preferred person is a sodium perchlorate.
Said composition also comprises the flame quencher.This flame quencher is selected from preferred phosphoric acid salt, and as list, disodium salt, ammonium salt and hexametaphosphate, most preferably the person is an ammonium salt.The oxidizing agent solution that flame quencher of the present invention both can be used for the P-5 emulsion formulations mutually in, also can be used as one of composition of solid dopants, or both all can.
Water ratio in the aqueous solution of this inorganic oxidant salt is preferably based on the 5-16% of blasting explosives composition gross weight (weight).
Fuel comprises the mixture of the waxy substance (usually indication be Microcrystalline Wax and paraffin) of straight chain and side chain mutually, emulsifying agent and comprise paraffin oil alone or with commerce in be known as the fuel that the residue of crude oil of the low sulfur content of LSHS cooperates.Known this fuel makes bilayer more pliable and tougher when suffering pressure, therefore helps to reduce the shear-sensitive degree of doping emulsion.
Because a large amount of doping agents, the emulsifying agent that uses in composition of the present invention is given the stability of composition height especially.The emulsifying agent that uses with the predetermined molar ratio example according to other raw material comprises particularly preferred condenses based on maleation polyisobutene tensio-active agent and alkanolamine, and produces with code name E-475/E-476.Its amount ranges is 0.5-3.0%, and preferable range is 1.0-3.0%.
Other emulsifying agent comprises by long-chain fat family carboxylic acid and molecular weight being the polymkeric substance of the polyoxyethylene glycol condensation prepared between the 400-3000, the ester of sorbyl alcohol and longer chain fatty acid, as polyoxyethylene-sorbitan mono-oleate (SMO), sorbitan trioleate (STO) or Arlacel-83 (SSO), phosphatide, as soybean lecithin (Qi oxazoline of SL) Huo or imidazolidine derivatives, lanolin, the tensio-active agent compatible that a kind of steroid product that obtains from wool fat or phosphoric acid ester can be buied with different trade marks with other with paraffinic fuel.
