摘要
以白皎煤矿21采区2114综采工作面跨采底板主干巷道的工程实践为背景,应用理论分析和现场实测的手段,研究了跨采巷道围岩变形的特征和破坏机理,并在现场试验了"高强让压锚杆+W型钢带+鸟窝锚索"的加固方案,解决了该矿的支护难题。
Taking Baijiao Coal Mine 2114 fully mechanized working face in 21 mining area of crossing mining floor main roadway engineering practice as a background,through the application of theoretical analysis and field measurement method,the paper studies roadway surrounding rock deformation characteristics,and failure mechanism,and ＂high-strength yielding bolt＋bird-nest anchor rope＋W type steel strip＂roadway reinforcement scheme is applied in the field test,which solves the aforementioned technical problems.
