classification:
emulsion explosive can be classified into rock emulsion explosive, coal mine permissible emulsion explosive and opencast emulsion explosive.
rock emulsion explosive applies to blasting engineering in no danger of gas explosion or dust explosion.
coal mine permissible emulsion explosive applies to blasting engineering in danger of gas explosion and dust explosion.
opencast emulsion explosive applies to open-pit mining blasting engineering.
