摘　　要：为解决盛平煤矿工作面巷道支护的问题,以盛平煤矿地质条件为依据,利用数值模拟软件建立了巷道在不同支护方式下的数值模型,得到了不同支护条件下巷道围岩变形、应力分布及塑性区分布变化规律,并分析锚杆和锚索在巷道支护中所起的作用。数值模拟结果表明:锚杆、锚索能够很好的起到挤压悬吊作用,形成了以锚杆为主的承载圈,在锚索的作用下,进一步增强了围岩的组合效应和抗变形能力。锚杆、锚索联合支护对巷道围岩控制起到较好的作用。In order to solve the problem of roadway support in Shenping Coal Mine, based on geological condi- tions of this mine, numerical simulation software was used to establish a numerical model of roadway support in different ways, the roadway deformation was obtained under different support conditions, stress distribution and variation of the distribution of plastic zone, and the role of bolt and anchor playing in roadway support was ana- lyzed. The numerical simulation results showed that bolt and anchor could play a good role in squeezing sus- pension by forming a bearing circle mainly on the bolt with the role of anchor, it further enhances the com- bined effects of rock and resistance to deformation, the combined support of bolt and anchor plays a relatively good role in roadway control.
