Abstract

The invention discloses a powdery emulsion explosive for on-site mixed loading. The powdery emulsion explosive comprises powdery latex substrate and a sensitizer. The mass ratio of the powdery latex substrate to the sensitizer is 30: (1-1.5). The powdery latex substrate comprises sodium nitrate, crystal modifiers, flame inhibitors, water, compound additives, oil-phase materials, compound emulsifiers and emulsification assistants. The sensitizer comprises expanded perlite, carboxymethyl cellulose, polyvinyl alcohol, ammonium bicarbonate, phosphoric acid, water, urea and ammonium nitrate. The invention further discloses a preparation method of the powdery emulsion explosive for on-site mixed loading. The emulsion explosive has high detonation velocity, brisance and coupling degree and few fumes; cost is low, the state of the explosive is hard, and work capacity is high; less poisonous gas is generated during preparation, safety of operators can be improved, and environment protection can be realized; the preparation process is simple and easy to operate.

Description

technical field [0001] The invention relates to an emulsion explosive and a preparation method thereof, in particular to a powdery emulsion explosive for on-site mixing and a preparation method thereof, and belongs to the field of explosive manufacture. Background technique [0002] Mining mining technology refers to the mining technology of valuable natural mineral resources by manpower or machinery. According to the different burial depths of ore deposits and the requirements of technical and economical rationality, mining techniques can be divided into open-pit mining and underground mining. Open-pit mining is used for the parts close to the surface and shallow buried, and underground mining is used for deep parts. Among them, the use of blasting operations in coal mines to mine mines is currently one of the methods that are more convenient to operate and have quicker results. [0003] Blasting operation is a very important and arduous work in various operations of minin...
