At mid-1980s, many large and middle open pits in China began to equip bulk emulsion explosive trucks, and progressively realized site manufacturing and mechanical charging of mining explosives, which, to a great extent, increased the blast and mining production efficiency, and promoted Chinese mining blast technical progress. The site manufacturing and charging technology for bulk emulsion explosives may considerably simplify components and preparation process of mining explosives, realize mechanization of explosive preparation and charging blast hole, improve safety during manufacturing, transportation and handling of explosives ...
