| 摘 要： | 随着埋深的增加,矿山主巷道周围的位移逐渐增大,应力集中情况愈趋显著,因此,需对主巷道的稳定性进行分析。采用数值模拟的方法,模拟计算了不同厚度素混凝土喷层支护下巷道应力的重新分布情况,为矿山进行主巷道支护提供了依据。

| Abstract: | In Nanjing Lead-Zinc-Silver Mine,the displacement and stress in the rock mass around main roadway are increasing with the increase of depth,therefore,the stability analysis of roadway's surrounding rock is necessary.When roadway is supported by sprayed concrete with different thickness the stress redistribution of the surrounding rock was simulated and calculated using the method of numerical simulation.The studied results provide the basis for the support of main roadway in this mine. |
