Abstract:

According to the transfixion construction of 2nd chute in open pit mining field of Zijinshan gold-copper deposit, the paper elaborates in detail the transfixion blasting construction of chute VRC method. Considering the influence of blasting time limit, a feasible solution was proposed. By the smooth chute transfixion experience and the analysis on the construction, the attentions for VRC method in chute transfixion blasting operation are summarized.
