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。
Based on the engineering background of the typical tunneling of deep mining mines in Meng-Shan area, the method to determine the reasonable roof distance of tunneling is researched and applied. Practice has proved that the combination of numerical calculation and downhole test can determine the empty top distance of roadway excavation reasonably and provide an effective way to realize roadway safety and rapid tunneling.
