摘要
针对大采高工作面顶板围岩各岩层之间胶结能力弱、巷道围岩大面积垮落的特点,以西山煤电西曲矿6#煤巷道为研究对象,运用数值模拟和工程实践相结合的研究方法,分析研究巷道围岩最佳的支护方案。研究表明,采用锚杆组合梁与锚索组合拱相互耦合的支护方案,能够有效控制大采高巷道围岩变形,巷道围岩稳定性得到保证。
In view of the characteristics of weak cementing ability between rock strata of roof surrounding rock of big mining height working face and large area collapse of roadway surrounding rock, taking No. 6 coal roadway in Xiqu Coal Mine of Xishan Coal Power Group as the research object, the research method, combining numerical simulation and engineering practice, was used to analyze and study the best support scheme of roadway surrounding rock. The research shows that the support scheme of coupling bolt composite beam with anchor cable composite arch can effectively control the deformation of roadway surrounding rock and ensure the stability of roadway surrounding rock.
