| 摘 要： | 某矿五采区运输上山巷道布置在2#煤层泥岩底板中,遇水易膨胀,针对其支护难点,基于锚杆支护的紧固理论及组合拱理论,以及金属支架的柔性支护特性,对巷道断面尺寸及支护方案进行设计,设计出锚喷与U型钢棚联合支护方案,在后期的掘进及使用过程中表现出了良好的支护效能。

| Abstract: | In a mine,the transportation roadway is arranged in the mudstone floor of 2×coal seam,which is easy to expand when encountering water.Aiming at the difficulties of support,based on the fastening theory and combined arch theory of bolt support,as well as the flexible support characteristics of metal support,Based on the design of roadway section size and support scheme,the combined support scheme of bolting and shotcreting and U-shaped steel shed is designed,which shows good support efficiency in the later excavation and use process. |
