Gelatinous emulsion explosive for drilling shaft and preparation method of gelatinous emulsion explosive

Abstract

The invention relates to gelatinous emulsion explosive for a drilling shaft. The gelatinous emulsion explosive comprises the following components: ammonium nitrate, ammonium sulfate, ammonium chloride, ammonium carbonate, ammonium bicarbonate, ammonium thiosulfate, ammonium thiocyanate, sulfamic acid, ammonium phosphate, ammonium sulfate-nitrate, ammonium phosphate-nitrate, calcium ammonium nitrate, ammonium acetate, ammonium oxalate, ammonium tartrate, ammonium citrate, sodium nitrate, calcium nitrate, urea, dicyandiamide, glycine, methionine, lysine, an ethylene vinyl acetate copolymer, pentaerythritol tetranitrate, trinitrotoluene, nitrogen triiodide, potassium perchlorate, ammonium perchlorate, aluminum powder, titanium powder, iron powder, copper powder, zinc powder, tin powder, mixed rare earth, oil phase, an adhesive additive, a flame inhibitor, a composite gelatinizing agent, an emulsifier, a sensitizing agent, a stabilizing agent, micro hollow spheres and water. Due to addition of raw materials such as the flame inhibitor, the stabilizing agent and the mixed rare earth, the primary explosion sensitivity of the explosive is improved, the detonation resistance and the stability of the explosive are improved, and safe production of mines can be relatively well ensured.

Description

technical field [0001] The invention relates to a colloidal emulsion explosive for well drilling and a preparation method thereof, belonging to the technical field of deep well drilling. Background technique [0002] Emulsion explosive is to use the effect of emulsifier to disperse the droplets of oxidant salt solution evenly in the oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres to form a water-in-oil emulsion-like explosive. , is a new industrial explosive developed in the 1970s. The earliest emulsion explosives were non-detonator-sensitive and had to be detonated with the help of relay primers. Later, with the in-depth research on emulsion explosives, the emulsion explosives developed in the later stage also have detonator sensitivity, and have good water resistance, good explosive performance, low mechanical sensitivity and good safety, and the cost is lower than that of water.

Problems solved by technology

[0003] At present, emulsion explosives are commonly used in mine mining and well drilling. The existing emulsion explosives not only result in high production costs but also low safety factors due to the relatively high price of raw materials used in them.
