摘要
凤凰山煤矿一五一盘区变电所受综采工作面动压影响,两帮煤体破碎发生移近,严重影响变电所安全使用和整个盘区的正常生产,通过分析变电所变形情况和煤体内部结构,采用注浆配合对穿锚索对煤体进行加固处理,成功解决了窄煤柱变形问题。
Electric power substation at 151 panel mining in Fenghuangshan Coal Mine is affected by the dynamic pressure of fully mechanized working, and its two-sided coal bodies were broken and moved, which seriously influenced the safe use of substation and normal production in the whole plate. This paper analyzed substation deformation situation and internal structure of coal bodies, and decided to use grouting and two-ended cables to perform reinforcement treatment, which can successfully solve the deformation problem of narrow coal pillar.
