摘要
针对深井大断面全煤巷道支护困难的问题,根据某矿3107工作面顺槽地质条件,综合锚杆系统、锚索系统、桁架系统及表面控制系统各自优点,设计出锚杆+锚网+钢带+桁架+高强锚索支护方案,并采用该支护方案对沿底掘进巷道顶板及两帮进行支护。
In view of the difficult problem of large coal roadway support in deep shaft, according to the geological conditions of 3107 working face crossheading in a coal mine, comprehensive respective advantages of bolt system, cable system, truss system and surface control system, designs the anchor ＋ steel belt ＋ truss ＋ high strength anchor cable support scheme, and the support scheme is adopted to support the roof and two sides along the roadway.
