从爆破过程、岩体破碎效果、根底残留情况以及后拉范围方面

取得了较好的效果

提升了挖运作业效率

降低了采矿成本.

Abstract

In the open-pit coal mining

the existence of layered rock mass poses certain challenges for blasting excavation. This paper was based on theoretical analysis of charge structure

LS-DYNA3D numerical simulation experiment and field industrial test. Two kinds of blasting charge structures of layered rock mass in Heishan Coal Mine of Xinjiang were studied. The results show that the airdeck charge of layered rock mass is better than the column charge

which improves the effective energy utilization rate of blasting. In terms of blasting process

fragmentation effect

root residue conditions and back-tension range

good results have been achieved

which improve the efficiency of excavation operation and reduce the mining cost.
