Vokhmin S.A., Kurchin G.S., Kirsanov A.K., Deryagin P.A. Calculation of parameters of drilling and blasting operations for horizontal and incline working

Abstract

The authors suggest a method for calculation of parameters of drilling and blasting operations for under-ground mine working which differs from existing ones in the fact that parameters are calculated not on a specific consumption of explosives, but on a radius of a fracture zone.

Keywords

Explosive, drilling and blasting operations, blasthole, charge, explosion.
