摘要
针对9-3012区段回风平巷围岩变形破坏严重,影响工作面正常生产的情况,综合采用钻孔取芯、力学试验及现场监测的手段对巷道破坏原因进行分析,提出"锚索+钢带+菱形网+钢梁+钢筋梯+组合锚索"联合支护方案。现场监测表明巷道围岩控制效果良好。
In view of the serious deformation and damage of surrounding rock of the return air roadway in section 9-3012,which affects the normal production of the working face.In this paper,drilling coring,mechanical experiment and on-site monitoring are used to analyze the causes of roadway failure,and the combined support scheme of "anchor cable + steel belt + diamond mesh + steel beam + steel ladder + combined anchor cable" is put forward.Field monitoring shows that the surrounding rock control effect of the roadway is good.
