摘要
针对耿村煤矿12200工作面的地质条件及开采技术,对大断面巷道进行了支护设计,通过理论计算和工程类比法对锚网支护参数进行了优化设计;得出了巷道锚网支护参数及巷道棚距;有效地控制了巷道变形,改善了通风、运输、行人条件,防灾抗灾能力增强。
According to the geological conditions and mining technology of 12200 working face in Gengcun coal mine , thispaper made the support design of large section roadway , the anchor net support parameters are optimized through theoretical calculation and engineering analogy method; get the bolt mesh supporting parameters and the roadway shed distance;roadway deformation is controlled effectively, improve the ventilation, transportation, pedestrian conditions, enhance dis-aster prevention capabilities.
