提出的掘进方法和巷道保护能消除支承压力的危害影响和保证支护的最好条件。其实质如下,在工作面随后≥20～25m处掘进运输平巷。平巷处于煤层底板岩体上,使梯形顶梁或锚栓的部段置于煤层底板水平上。从平巷到煤体顶板的距离按倾斜≥10～15m。平巷附近不砌筑石带, The proposed excavation method and roadway protection can eliminate the harmful effects of bearing pressure and ensure the best conditions for support. Its essence is as follows, then digging in the working face more than 20 ~ 25m transport lane. The lanes lie on the rock mass of the coal floor so that the sections of the trapezoidal roof beam or anchor bolt are placed on the floor of the coal seam. The distance from the roadway to the coal roof should be ≥10 ~ 15m. No masonry near the lanes,
