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。
Based on the engineering practice of 2114 fully mechanized coal mining face with floor crossings in Baijiao Coal Mine 21, the characteristics and failure mechanism of surrounding rock deformation in cross-mining roadway are studied by means of theoretical analysis and field measurement. “High-strength pressure bolt + W-type strip + bird’s nest cable ” reinforcement program to solve the mine’s support problems.
