Jan 11 2011nbsp018332Therefore considering the fact that open cut blasting is mostly successful in mines it should be feasible to use a much higher specific charge such as 3.0 kgm 3 in mining production blasting. If so when the cost in drilling and blasting is increased by a certain amount the energy and cost in crushing and grinding might be largely reduced.
