斜沟矿大断面回采巷道锚杆-锚索联合支护研究

Combined Support of Bolt and Anchor Cable in Large Section Mining Roadway in Xiegou Coal Mine

以斜沟矿12513综采工作面运输巷道为研究对象,通过FLAC 3D模拟软件分析和现场实践,对12513综采工作面回采巷道锚杆锚索联合支护问题进行研究。根据目前现场锚索施工的最佳长度,设计了回采巷道在矿床中的合理位置,配合现场常用的支护材料,优化了锚杆-锚索联合支护的技术参数,为矿井的设计施工与生产管理提供了参考。

Taking the transportation roadway of 12513 fully mechanized mining face in Xiegou Coal Mine as the research object,through the analysis of FLAC 3D simulation software and field practice,the problem of combined support of anchor bolt and anchor cable in 12513 fully mechanized mining face is studied. According to the optimum length of anchor cable construction at present,the reasonable position of mining roadway in the deposit is designed, and the technical parameters of bolt-anchor cable combined support are optimized with the support materials commonly used in the site. It provides a reference for the design,construction and production management of the mine.
