摘要
将太原煤气化集团华苑煤矿10105综采工作面轨道顺槽出现的变形破坏问题作为研究对象,结合现场勘查、实验室分析等方式,研究巷道出现变形破坏的原因,设计了"恒阻让压耦合支护"返修支护方案。巷道返修结果表明,该方案可实现对巷道围岩变形的有效控制。
The problem of deformation and damage of the working surface of Huayuan Coal Mine 10105 was studied,and the causes of the deformation and damage of the roadway were investigated in the field investigation and laboratory analysis,and the constant allowable pressure coupling support reworking support scheme was designed.The repair results indicated that the scheme could achieve effective control of the deformation of the surrounding rock roadway.
