结合陈四楼煤矿 2 4 0 1工作面机巷的具体地质条件 ,对煤巷锚杆支护机理进行了研究 .指出在顶板岩石强度较低的情况下 ,采用高强锚杆支护系统 ,并选择合理的锚固方式 ,可以有效地控制围岩变形 ,保持围岩稳定 .主要介绍了回采巷道锚杆支护的设计思路 ,采用数值模拟方法确定锚杆支护参数并在实施过程中对围岩变形进行监测 .工程实践表明 :应用锚杆支护与棚式支护相比 ,能有效改善围岩的稳定性 ,取得了良好的支护效果 .
Combined with the concrete geological conditions of 2 4 0 1 mechanized roadway of Chen Silou coal mine, the bolting support mechanism in coal roadway is studied, and it is pointed out that in the condition of low roof rock strength, Selecting a reasonable anchoring mode can effectively control the deformation of surrounding rock and maintain the stability of the surrounding rock.It mainly introduces the design idea of bolt support in mining roadway, and uses the numerical simulation method to determine the bolt supporting parameters. Deformation and monitoring.The engineering practice shows that the application of rock bolt support can greatly improve the stability of surrounding rock and achieve good support effect compared with roof support.
