摘要
顾桥矿井在北一11-2采区施工过程中,由于该煤层顶板岩性较差,对三岔门(四岔门)巷道支护提出新的课题。设计采用了U型钢支架加锚索联合支护。实践证明,这种支护效果明显,在新一轮快速建井中值得推广使用。
In the construction process in North No. 1, 11 - 2 mining area, Guqiao Coal Mine, because the roof lithology in coal seam is poor, a new topics is proposed for the roadway support at three branch cross - hole （four branch cross - hole）. The combined support with U - steel support and cable is designed and applied. The practice proves that the support effect is obvious. It is worth recommeding in a new round of rapid construction.
