Abstract

The invention discloses an emulsion explosive for exploitation, and the emulsion explosive comprises the following components in percentage by weight: 50 to 65 percent of ammonium nitrate, 3 to 10 percent of sodium nitrate, 2 to 10 percent of oil phase, 5 to 10 percent of water, 0.2 to 4 percent of a sensitizer, 3 to 10 percent of a viscosity reducer and 3 to 10 percent of a thickening agent. According to the invention, aiming at the problems of serious explosive return phenomenon, environmental pollution caused by explosive powder and the like, various components in the material and properties thereof are reasonably blended and optimized according to specific requirements of the explosive, so that a corresponding new emulsion explosive for exploitation is created, which is an objective need of a development period at present and even in the future.

Description

technical field [0001] The invention relates to the field of mining, in particular to an emulsion explosive for mining. Background technique [0002] Underground blasting is often encountered in mining and other projects. For deep hole blasting, choose to charge upwards for deep holes. When charging upwards, because the traditional emulsion explosives are colloidal, they have high viscosity and poor fluidity. , its pumping problem has not been effectively solved, so the blasting charges in underground mines are still based on powdered explosives. Pneumatic mechanical charging is used to load powdered explosives, and powdered explosives, because the powder is not viscous, the phenomenon of drug return is serious, especially when filling the upward hole, the rate of drug return and drop rate is as high as 30-40% under normal circumstances. %, serious waste of explosives. Due to the serious powder return, the actual filling amount of explosives in the blast hole is far less t...
