| 摘 要： | 张集矿九层煤厚度与倾角变化大，为能用单体柱一次采出３．２ｍ厚的煤层，确保采面、顺槽及底板巷迟支护的完好，作者运用非线性有限元方法研究了不同采高及倾角条件下的采场围岩应力的分布特征，从而提出了相应的控制策略，并得到了成功应用。

| Abstract: | The thickness and dip of Seam 9 in Zhangji Colliery vary grcatly.In order to extract the 3.2m-thick coal seam at one time using individitial props and insure the faces gateroads and floor roadways to be supported properly.this paper studies the stress distribution characterlstics of surrounding rock in faces with different shear height and dip using non-linear finite element method and has been successfully applied |
