A foremost element of the mining process is breaking up the rock This breakup is accomplished by detonating volatiles set in blast holes The rock face to be gusted is typically 40feet in width by 20 to 25feet high A premeditated pattern of 40 to 50 horizontal holes are drilled for the dimensions of 2 inches wide by 12 to 14feet deep...
