摘　　要：在铜坑矿９１号矿体大直径深孔采矿法试验过程中，对采场凿岩硐室围岩的应力状态和岩移进行了监测。文中介绍了监测结果，用弹性和弹塑性理论研究了硐室围岩的应力状态，分析了硐室的稳定性和支护系统的作用。In the test of the large diameter longhole mining of No.91 orebody at Tongkeng mine,the stress and the displacement of wall rock at the stope drilling chamber were monitored.An introduction to the results is made in this paper.Meanwhile,the stress state of the chamber wall rock is studied by the elastic theory and the elastic plastic theory.The stability of the chamber and the effects of support system are analyzed also.
