摘　　要：深部软岩巷道频繁发生顶板下沉、底鼓、两帮移近等大变形;在相邻巷道地应力和采动应力的共同作用下,变形更加剧烈,严重影响了煤炭的安全开采;基于山西大同李家窑煤矿的地质条件和巷道破坏特征,采用综合数值模拟和现场观测的方法对巷道变形破坏进行分析;对深部软岩巷道在相邻工作面采动过程拟定控制措施;探究一次支护方案下巷道围岩变形及裂隙发育特征,并对其效果进行评价。Aiming at the serious deformation of roof subsidence,floor and two sides’convergence under the interaction of ground stress and mining stress in adjacent deep soft-rock roadway,the author makes an analysis of roadway deformation and failure by means of numerical simulation and on-site monitoring based on the geological conditions and roadway failure characteristics in Shanxi Datong Lijiayao Colliery,proposes the control measures for deep soft-rock roadway during mining in the adjacent working face,explores the roadway surrounding rock deformation and fracture development characteristics under primary support scheme and evaluates its effects.
