| Abstract: | According to the mechanical properties and geological features of thousands-meter- deep-well ore body and its surrounding rocks in Dongguashan copper mine, the selection of long-hole blasting scheme is introduced in this paper. The design of blasting parameters, charge structure, priming network and technique for room stope is introduced. Based on the application of bunch-long-hole blasting technique and the adjustment of blasting schemes, the blasting technical and economic indexes, as well as the control effect for blasting, can be improved. |
