摘　　要：以西山煤矿第一水平运输大巷为研究背景,通过数学计算与数值模拟手段相结合的方法,研究了顶底板岩层性质变化引起的复杂应力扰动下巷道围岩的稳定性,确定了锚杆锚索联合支护配合混凝土的加强支护方案。模拟结果和工程均证明了方案的可行性,确保了围岩的稳定性。Taking the first horizontal transport roadway of Xishan Coal Mine as the research background, through the combination of mathematical calculation and numerical simulation, this paper studied the stability of roadway surrounding rock under complex stress disturbance caused by the change of roof and floor rock properties, and determined the reinforcement support scheme of bolt and cable combined support and concrete. Both the simulation results and the project have proved the feasibility of the scheme and ensured the stability of the surrounding rock.
