摘要
精密作业VCR法技术方案是基于束状孔球形药包爆破技术的新型采矿技术。应用三维数值分析软件,对精密VCR法在不同开采阶段矿岩的受力状态进行分析,为矿山开采设计提供参考。
VCR with precision drilling is a new mining technology based on the bundle- hole spherical charge blasting. In this paper, the stress states of mine rock with different mining stages using VCR method are analyzed by a 3 - D numerical analysis software. The results can provide reference for the mining design.
