摘要
为探究厚风化煤层的安全稳定开采,从回采巷道支护技术的角度着手,针对某煤矿厚风化煤层开采工作中的风险问题,对其支护技术进行优化设计,主要以“直墙拱形”断面全锚索支护形式进行支护作业。从实际应用测试结果来看,针对厚风化煤层的回采巷道支护技术具有一定的技术优势与可行性,预计其在今后的类似场景下也将具有一定的应用价值。
In order to explore the safe and stable mining of thick weathered coal seam,starting from the perspective of the support technology of the back-mining roadway,we optimize the design of the support technology for the risk problems in the mining of thick weathered coal seam in a coal mine,mainly in the form of"straight-wall arch"cross-section of the full-anchor cable support for the support operation.From the actual application test results,the tunnel support technology for thick weathered coal seam has certain technical advantages and feasibility,and is expected to have certain application value in the future similar scenarios.
