摘要
由于受断层及采空区的应力影响,煤体围岩破碎、顶板不完整、裂隙多,易造成密闭、高冒巷封堵不严密,存在漏风等安全隐患,为此,对密闭、高冒巷进行注浆加固,防止漏风,消灭了煤炭自然发火事故,确保了矿井的安全生产。
Aiming at the potential safety hazards such as leaky sealing and plugging in high carved roadway and air leakage due to broken surrounding rock,incomplete roof and much fracture,the authors propose the grouting reinforcement on sealing and high carved roadway,which prevents air leakage and spontaneous ignition accidents,and guarantees the safety production.
