摘 要:为保障新元矿9105工作面进风顺槽大断面松软煤层巷道围岩的稳定,基于巷道围岩变形机理及松软煤层大断面巷道支护原则,进行顶底板及两帮锚杆索各项支护参数设计,并在支护方案实施后进行围岩变形监测。结果表明:支护方案实施后,巷道掘进及工作面回采期间,围岩变形量均较小,保障了巷道围岩稳定,满足回采使用要求。In order to ensure the stability of the surrounding rock of the large cross-section soft seam roadway in air-intake crossheading at 9105 working face of Xinyuan Colliery,the author designs the support parameters in the roof and floor and the two sides of bolts based on the deformation mechanism of roadway surrounding rock and the principle of supporting the large section roadway in the soft coal seam,and monitors the surrounding rock deformation after the scheme implementation of the support,whose results show that the stability of the roadway surrounding rock is guaranteed with small deformation during the roadway excavation at the mining face.
