摘要
异形工作面在回采过程中会遇到诸多困难,诸如工作面采长变化、支架安装、撤除及工作面旋转等复杂情况挑战,安全管理难度大。许平煤业高庄矿在3个煤柱面合并回采过程中,综合运用悬移支架连续开采、过老巷及巷道超前支护等综合技术手段,实现了安全回采。
Special - shaped working face will encounter many difficulties during the process of working face in mining, such as working face mining length change, support installing, removal and face rotation challenge for complex circumstance, the safety management is difficult. This article introduces the Xuping Coal Company Gaozhuang Coal Mine in three cylindrical combined extraction processes, the integrated use of suspended support continuous mining, passing through old roadway and advancing support and other comprehensive technical measures, safety mining is realized.
