深部软岩回采巷道破坏机理及锚注技术应用

Failure Mechanism of Deep Soft Rock Roadway and The Application of Anchor Grouting Technique

龙矿集团梁家煤矿为"三软"地层,回采巷道的变形破坏直接影响着工作面及回采巷道机电设备的迁移和采煤工作面的正常推进。通过对工作面回采巷道变形破坏的机理进行分析,研究实践出了一套较为成熟的软岩支护技术,并配套了科学的矿压观测及记录,取得了良好的安全效益和经济效益。

Longkou Mining Group Liang Jia coal mine is located in"Three Soft"strata,the deformation and failureof roadway directly affects the electromechanical equipment migration and the normal mining.Based on the failuremechanism of roadway deformation are analyzed.The research and practice of a set of relatively mature soft rocksupporting technology were taken,which get the good security and economic benefits.
