煤矿高应力巷道支护方法研究

Study on Supporting method of High Stress Roadway in Coal Mine

矿井开采深度的不断增加,巷道所处的应力环境越来越差。在高应力的作用下,巷道严重变形,直接影响工作面的正常安全生产。以永定庄煤矿8106工作面2106皮带巷为研究背景,通过FLAC^(3D)数值模拟软件对三种锚杆支护方案进行了模拟,作为合理的支护方案选项。结果表明,支护方案能够有效控制工作面围岩变形。

The stress environment of coal mine roadway is getting worse and worse,with the progress of the mining.Under the action of high stress,the roadway can produce serious deformation,which affects the normal safe production.This paper takes the 2106 belt of 8106 face in Yongdingzhuang Coal Mine,as the research background,simulates three kinds of bolt supporting schemes,by means of he numerical simulation software FLAC3D,and determines the reasonable plan as a choice.The results show that this method can effectively control the deformation of surrounding rock.
