Abstract
The invention belongs to Permilted emulsificated explosive for coal mine.What play sensibilized in the explosive is organic blowing agent.Sensitization bubble in this kind emulsion explosive for coal mine is careful, is evenly distributed, and the sensitizing time is short, and the sensitization after effect is little.Reach more than 1 year the natural storage period of this kind explosive, and blast performance and security are better than the emulsion explosive for coal mine made with perlite or Sodium Nitrite.The cost of used organic blowing agent is perlitic 11%.Explosive series of the present invention can be used for that biogas is arranged, the ore deposit of coal dust outburst danger, and safety performance is higher.
Description
The present invention relates to a kind of Permilted emulsificated explosive for coal mine, particularly high safety explosive allowable in the mine that biogas, coal dust outburst danger are arranged.
The blasting performance of existing Permilted emulsificated explosive for coal mine is stable inadequately, and package stability is relatively poor, and the explosion power is little, and manufacturing cost is higher.Adopt pearlstone as sensitizing agent in the existing Permilted emulsificated explosive for coal mine.Perlite is an inert substance, and the blast performance of explosive and package stability are reduced, and only be 8 months natural storage period.Existing Permilted emulsificated explosive for coal mine is afraid of extruding in process of production, dress volume difficulty, and environmental pollution is bigger simultaneously, and it is healthy to influence the workman.With the explosive of perlite as sensitizing agent, because perlitic costing an arm and a leg, manufacturing cost is higher.Also have in some emulsion explosive for coal mine and contain glass microsphere or plastic microsphere, manufacturing cost is expensive especially.
The objective of the invention is to prepare the higher Permilted emulsificated explosive for coal mine of a kind of security, the blast performance of this emulsion explosive and package stability are improved, the dress volume easily can continuous production, and is free from environmental pollution, low cost of manufacture.
The present invention realizes like this.Contain organic blowing agent in the Permilted emulsificated explosive for coal mine of the present invention, it is to mix explosive as sensitizing agent.The gas that this organic blowing agent sent is rare gas element, not can with other composition generation chemical reaction in the explosive, so the excellent storage stability of explosive.With the sensitizing of this organic blowing agent as sensitizing agent, the time is short, and sensitization bubble is careful, is evenly distributed, and bubble is difficult for assembling or disappearing, and sensitization aftereffect acts on little.The diameter of bubble is 5～15 microns, and number of bubbles is 800～2000 in every square millimeter of microscopically.Emulsion explosive of the present invention can be stored naturally and reach more than 1 year, and it is not afraid of extruding, and dress licks Cheng Rongyi and realizes mechanize, and production can be carried out continuously.Through overtesting, sympathetic detonation distance of explosive of the present invention is 70mm; Explosion velocity is 3863m/S, and brisance is 13.42mm; Quick-fried power is the 267ml(milliliter), this illustrates that the Permilted emulsificated explosive for coal mine made from organic blowing agent is better than the emulsion explosive made from perlite or Sodium Nitrite.The consumption of organic blowing agent is few in emulsion explosive of the present invention, only accounts for 0.05～1.00% of charge weight, and material is cheap, and the expense of purchasing of used organic blowing agent only is perlitic 11%.Existing emulsion explosive for coal mine all need add an amount of perchlorate, and nitric ether etc. reduce the security of explosive.In the emulsion explosive of the present invention, can not add perchlorate and nitric ether etc., thereby the security of explosive increases substantially.
It is as follows that the present invention makes the prescription of coal blending ore deposit Permilted emulsificated explosive:
Ammonium nitrate 60～65%
SODIUMNITRATE 10～15%
Urea 0.5～2.0%
Water 7～9%
Composite fuel oil 4～5%(is Vaseline 40% wherein; Paraffin wax 40%; Machine oil 20%)
Emulsifying agent 1.5～2.0%
Organic blowing agent 0.05～1.00%
Repone K 5～8%
Additive 0.1～0.5%
Organic blowing agent can be one of following several organic compound: (1) organic azo-compound; (2) organic sulfonyl hydrazines compound; (3) organic nitroso compound.
The manufacturing process implementation data of emulsion explosive of the present invention is as follows:
Interior phased soln temperature: 100 ± 5 ℃;
Oil phase temperature: 80～85 ℃;
The reinforced time: 1～1.5 minute;
Emulsification stirring speed and time: stir in turn according to following
500～700 rev/mins were stirred 1～3 minute;
1300～1500 rev/mins were stirred 5～9 minutes;
500～700 rev/mins were stirred 1～3 minute.
When organic blowing agent fed intake, the temperature of emulsion explosive was 40 °～80 ℃, stirred 5～10 minutes.
