摘　　要：利用数值模拟软件建立采区的数值模型,得出所研究水平的采场安全系数分布图,将安全系数划分为不同级别,在不同的安全系数分级级别下制定相应的巷道支护方案,为井下巷道支护选择提供参考。The numerical model of mining area is set up by using numerical simulation software and the stope safety factor coefficient distribution of the research level can be obtained. The safety factor is divided into different levels and the tunnel support schemes in different levels are formulated,which can provide the references for underground tunnel support.
