摘要
结合煤层顶板岩性和锚杆支护原理,对四台矿11#层回采巷道顶板管理上存在的问题进行了分析,指出了单一的钢棚式支护或锚栓式支护的不合理性,并就11#层回采巷道顶板支护的合理性进行了分析与探讨。
Connecting with the rock characters of the coal roof and the principle of the bolting, this paper makes analysis on the problems existing in the roof management of No.11 seam's stoping tunnel of Sitai Coalmine, points out the irrationality of the single steel-shed support or anchor bolt support, and probes into the rationality of the roof-support of No.11 seam's stoping tunnel.
