Abstract

The invention provides an environment-friendly type pellet powder, which is prepared from graininess ammonium nitrate 86-90wt%, diesel 4-5%, solid powder 4-5% and viscosifying agent 2-4% through proportioning, stirring 2-5 min at room temperature, mixing homogeneously, charging solid powder and viscosity increaser, stirring 1-2 min at room temperature, mixing homogeneously, discharging and packaging.

Description

technical field [0001] The invention relates to an environment-friendly viscous granular explosive. Background technique [0002] At present, in underground mining and blasting operations, explosives are often loaded by means of pneumatic mechanical charging. If the explosives used are powdered ammonium ladder explosives, the phenomenon of charge return will occur during the pneumatic charging process, which will not only waste a large amount of explosives, but also cause flying dust, seriously pollute the surrounding environment, and damage the health of operators. [0003] In order to solve the above problems, existing people have successfully developed T-1 type and M-2 viscous granular explosives, see (Wang Wenyou, Yun Zhuhui. Industrial Explosives. Beijing: Ordnance Industry Press, 1993.307-311.) (Cui Yong, Jiang Guorong. Research and Development of Viscous Granular Ammonium Nitrate Explosives Allowed in Coal Mine, Blasting Equipment, 2002, 31(4): 20-22.) (Li Mingneng, ...
