摘要
为了解决澄合百良旭升煤炭有限公司软厚煤层、破碎顶板大断面切眼锚杆支护问题,运用自稳隐形拱理论对切眼进行了锚网索联合支护参数设计,并通过Midas/GTS数值模拟软件验证了设计的可行性,为类似复杂条件下大断面切眼锚杆支护提供了理论依据。
To solve the problems of bolt supporting for large section open-off cut in soft thick coal seam in Chenghe Bailiang Xusheng Coal Co .,Ltd,the bolt-mesh-cable combined supporting was designed by the theory of self-stabilized hidden arch , and the feasibility of the design was verified by Midas/GTS numerical simulation .The research can provides theoretical ba-sis for bolt supporting of large section open-off cut in similar complicated conditions .
