随着煤炭开采深度不断加大 ,线性力学设计方法愈来愈不能满足软岩支护设计需要。在工程岩体力学理论基础上 ,采用软岩巷道工程的非线性力学耦合设计 ,解决了鹤壁矿务局冷泉煤矿高应力节理化软岩巷道大地压、大变形、难支护的问题 ,并取得了良好的技术经济效益
As the depth of coal mining continues to increase, linear mechanical design methods are increasingly unable to meet the needs of soft rock support design. Based on the mechanics theory of engineering rock mass, the nonlinear mechanical coupling design of soft rock roadway project is adopted to solve the problem of large earth pressure, large deformation and difficult support in soft rock roadway of high stress joint and soft rock in Lengquan Coal Mine, Hebi Mining Bureau. A good technical and economic benefits
