近距离煤层采空区下回采巷道布置方式研究

Study on Layout of Mining Roadway under Goaf in Contiguous Seams

本文以汾西矿业集团宜兴煤业1201^-2工作面为背景,通过分析工作面地质情况,采取理论计算、数值模拟、现场试验分析的方法确定了布置2^#下煤回采巷道时应选用内错4~6m的布置方式,为矿井下层煤的巷道布置提供了合理的参数。

Based on the 1201^-2 working face of Yixing Coal Industry of Fenxi Mining Group, this paper analyzes the geological conditions of the working face and adopts theoretical calculation, numerical simulation and field test analysis to determine the layout of 4~6m staggered inside for the stoping roadway of No. 2 coal mine, which provides reasonable parameters for the layout of the roadway in the lower coal seam of the mine.
