针对孤岛面断层破碎带附近巷道围岩稳定性降低的特点,结合某矿孤岛工作面断层破碎带煤巷支护方式,提出了基于巷道表面位移、锚杆、锚索载荷的巷道支护工程质量检测技术,实测巷道围岩变形量在控制范围内,锚杆、锚索在支护过程中未超过额定载荷,现有的支护方式能够满足巷道支护要求,此类锚杆支护工程质量监测技术可为巷道支护参数的合理选择提供现场指导。
針對孤島麵斷層破碎帶附近巷道圍巖穩定性降低的特點,結閤某礦孤島工作麵斷層破碎帶煤巷支護方式,提齣瞭基于巷道錶麵位移、錨桿、錨索載荷的巷道支護工程質量檢測技術,實測巷道圍巖變形量在控製範圍內,錨桿、錨索在支護過程中未超過額定載荷,現有的支護方式能夠滿足巷道支護要求,此類錨桿支護工程質量鑑測技術可為巷道支護參數的閤理選擇提供現場指導。
