补连塔煤矿跨采大巷支护效果及数值模拟分析

Support Effect and Numerical Simulation Analysis of Over Roadway Mining in Bulianta Coal Mine

跨采前要对工作面运输巷进行加强支护并对支护效果进行分析,这对指导矿井实际生产具有重要意义。以神东补连塔煤矿实际开采条件为工程背景,运用FLAC^(3D)数值模拟软件对底板运输巷围岩在加强支护前后的变形进行了模拟分析,通过现场围岩位移监测对支护效果进行了评价。

It is necessary to strengthen the support and analysis of the supporting effect before the over roadway mining, which is of great significance to guide the actual production of the mine. The paper takes the actual mining conditions of Bulianta Coal Mine as the engineering background, the FLAC3D numerical simulation software is used to simulate and analyze the deformation of the surrounding rock in the straight groove of the bottom plate before and after strengthening support. The effect of supporting is evaluated by monitorinz the displacement of surrounding rock.
