| 摘 要： | 通过相似模拟试验、位移反分析与边界数值计算, 对锚杆支护全煤巷道进行稳定性分析。首先模拟了巷道开挖以后围岩变形, 利用位移反分析法确定初始应力与围岩变形模量及泊松比等参数, 根据边界单元法数值分析结果确定围岩松动圈范围, 然后对全锚支护煤巷围岩稳定性进行分析。

| Abstract: | Based on model test, displacement back analysis and BEM, an analysis of the stability coal roadway bolting is presented in this paper. After modeling the surrounding rock deformation of excavated roadway, initial stress, deformation modulus of surrounding rock and poision ratio are calculated by displacement back analysis method. The crush zone of surrounding rock is detected according to the results of BEM. The principle of whole bolting is used in desigh of bolt parameters. |

| Keywords: | coal roadway bolt deformation modulus displacement back analysis model stability BEM |
