  • Rock Boulder Blasting with Explosive

    Binary explosives are widely used for mudcapping for their added efficiency and safety Explosive initiation can be accomplished in a number of ways using safety fuse, electric blasting caps, or detonating cord The amount of explosive needed greatly depends on the rock size A range of 05 to 2 lb per cubic yard is a good estimate for use
