In normal blasting all holes do not blast at the same time. Bench blasting is normally carried out as short delay blasting. The firing pattern has to be designed so that each blasthole has free breakage. The firing sequence of a chevron pattern can radically alter the drilled burden and spacing into the blasted or effective burden (Be)
Jan 11, 2011· Therefore, 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 kg/m 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.
