摘要
针对大跨度切眼巷道支护的问题,结合开滦林西矿井田中深部的十、十一水平八石门8、9煤层合区的高应力强底鼓地质条件,分析总结了该条件下切眼多种支护形式的支护机理、施工方式及适用条件,重点对再生板大断面切眼巷道锚网支护形式进行研究实践,为类似围岩条件下巷道支护形式提供了借鉴。
Based on the problem of large span cut eye roadway support, combined with high stress strong floor heave geology of 10, 11 level Bashimen No. 8 and No. 9 coal seam in Linxi Mine, support mechanism, construction and application condition of multiple cut eye support under this condition were analyzed and summarized, regenerated plate large section cut eye roadway anchor net support was put into practice, which provided reference for roadway support under similar surrounding rock.
