摘要
针对平煤四矿大埋深高地应力巷道支护现状及围岩特点,总结了深井高地应力巷道支护原则,提出采用高强可变形让压锚杆+鸟巢锚索+W钢带支护技术控制深井巷道围岩的持续变形,并进行了支护试验。
Aim to the actuality about high stress roadway shoring and surrounding rock peculiarity in Fourth-coal mine＇s deepness-shaft, summarize principle on high stress roadway up deepness-shaft. And author sum up rules that it is adopting deformable high-strength press-anchor, bird＇s nest anchor-cable and W-metal band supporting technology, which can have an effect upon durative distortion in deepness-shaft roadway, finally practice in shoring at project.
