摘要
龙固煤矿中央泵房埋深-855 m,围岩变形大、支护风险高。为解决中央泵房硐室围岩的支护难题,基于先"柔"后"刚"的模式提出了锚网索喷让压+锚注联合支护方案,并分别通过理论分析和数值模拟对泵房围岩注浆效果进行了研究,取得了较好的围岩加固效果。
The Longgu mine central pump room is -855m in buried depth, which faces with the problem of large deformation of surrounding rock and supporting difficulty. In order to solve the difficulty problem of surrounding rock control in the central pump room, the combined support scheme of bolt-mesh-anchor - pressure relief ＋ bolt-grout have been put forward based on the model of ＂flexible＂ and ＂rigid＂, and studied respectively by theoretical analysis and numerical simulation of wall rock grouting effect,which obtain good effect of surrounding rock reinforcement.
