摘要
为进一步探究煤矿工作面动压巷道支护方案要点内容,以H煤矿工作面动压巷道现有支护方案存在的主要问题为研究对象,首先结合实际问题,应用仿真分析方法对巷道预留煤柱宽度进行优化,其次基于理论计算方法,对支护方案中锚索和锚杆的技术参数进行确定,以完成巷道支护方案的优化设计工作.从实际运行效果来看,优化后的巷道支护方案有效解决了围岩变形问题,具有一定的应用价值.
Abstract
In order to further explore the key points of the support scheme of dynamic pressure roadway in coal mine working face,the main problems existing in the existing support scheme of dynamic pressure roadway in a working face of H Coal Mine were taken as the research object.Firstly,combining with practical problems,simulation analysis method was applied to optimize the width of coal pillar reserved in roadway.Secondly,technical parameters of anchor cable and bolt in the support scheme were determined based on theoretical calculation method to complete the optimal design of roadway support scheme.From the actual operation effect,the optimized roadway support scheme can effectively solve the problem of surrounding rock deformation and is of certain application value.
