摘要
针对崔木煤矿深部高应力煤巷新掘巷道5 d内即出现大变形的问题,通过现场调研与理论分析的方法,分析了巷道大变形机理,并根据矿井实际情况提出高强预应力锚网索支护外加结构补偿措施,以提高支护承载结构的承载性能。
Aiming at the large studying the large deformation forward high prestress bolting deformation appeared mechanism by the way support with structure in new roadway within five days in Cuimu mine, of field investigation and theory analysis, putting compensation measures attached to improve the carrying capacity of surrounding rock.
