摘　　要：以蒙陕矿区深部开采矿井典型巷道掘进为工程背景,对巷道掘进合理空顶距离的确定方法进行了研究与应用。实践证明,采用数值计算与井下试验相结合的方法能够较合理地确定巷道掘进空顶距离,为实现巷道安全、快速掘进提供有效途径。Studied the method of determining a reasonable unsupported roof distance by taking typical deep coal mining conditions in Mengshan coal-mining area as engineering background. The industrial practice proved that the method combined with numerical simulation and roof behavior monitoring was reliable and provided an effective way to make the roadway tunneling quickly and securely.

关 键 词：大断面煤巷 合理空顶距离 快速掘进
