摘要
针对朱仙庄煤矿南翼Ⅱ水平开拓巷道围岩变形大、难以控制问题,应用应力解除法测试获得了该矿南翼Ⅱ水平地应力场分布规律并结合数值模拟试验分析了σHV型地应力场巷道布置与最大主应力的关系。
Aiming at the problem that surrounding rock deformation of development roadway is too large to control in the second level of Zhuxianzhuang mine. The distribution law of horizontal in-situ stress field has been got by using stress relieving method. The relationship between the roadway layout in the σHv type in-situ stress field and the maximum principal stress has been analyzed by combining with numerical simulation test.
