摘　　要：工作面切眼大跨度岔门支护是煤矿顶板管理的重中之重。随着煤矿开采逐步向深部方向发展,受地质构造、采空区、埋藏深度等诸多因素影响,冲击地压危险区域巷道支护条件越来越复杂,给大跨度岔门顶板支护带来了较大难度。结合姚桥煤矿矿井自然条件,在满足冲击地压支护标准的条件下,对工作面切眼大跨度岔门顶板采取了复合支护加固技术,取得了较好的应用效果。In response to the difficulty of roof supporting for large-span forked doors,combined with the natural conditions of Yaoqiao Colliery,and under the condition of meeting the standards for impact support,compound support and reinforcement technology is adopted for the cutting large-span forked door roof of the working face,which achieves good application results.
