摘要
平煤十一矿己二采区皮带下山采用的“阶梯式三相全锚索支护技术”,利用GRT-M6型M钢带加大顶板受力面积,利用岩体变形自动承压特性实现三向紧固,取得了较好的支护效果。
已 2 mining district,No. 11 Coal Mine, Pingdingshan Coal Industry Group Comp., belt down hill using step type three - phase anchor wire support technology which is using GRT - M6 M - belt to increase force bearing area, using rock deformation automatic bearing pressure characteristics to realize threephrase consolidation have achieved good results.
