| 摘 要： | 针对王行庄煤矿11091底抽巷现场实际情况,通过弹塑性理论分析,结合Hoek-Brown准则,计算出底抽巷帮部围岩松动圈厚度为2. 28 m;通过超声波测试与光学钻孔窥视测试方法得到松动圈厚度平均为2. 67 m。结果显示,理论分析结果与现场测试结果误差仅为15%,理论分析与实测结果一致。

| Abstract: | According to the actual situation of 11091 floor suction roadway in Wanghangzhuang Coal Mine,the thickness of loosening zone around the roadway side is calculated as 2.28m by elastic-plastic theory analysis and Hoek-Brown criterion,and the average thickness of loosening zone is 2.67 m by ultrasonic testing and optical borehole peeping test.The results show that the theoretical calculation result is only 15%less than the actual measured result,and the theoretical calculation result is consistent with the field measurement. |
