摘要
以淘锡坑钨矿区开拓工程为依托,采用workbench14.0有限元程序对处于大的节理裂隙下巷道开挖以及正常情况下开挖进行了数值模拟计算,分析了两种开挖情况下的围岩变化规律。结果表明,节理裂隙大的情况对巷道开挖的影响很小,与正常情况下的开挖支护要求只是略有不同。
On the basis of development practice in Taoxikeng Tungsten （）re Mine, the finite element program of Workbench 14.0 is used to conduct numerical simulation calculation for the case of tunnel digging under great joint fissure and the case of tunnel digging under normal condition. The regularity of wallrock change in the two cases is analyzed. The analysis shows the influence of great joint fissure on tunnel digging is slight. The requirement on support work is merely a little different from that under normal digging condition.
