| 摘 要： | 以张集矿11418(W)回采巷道为工程背景,分析了巷道顶板岩性相变较大、顶板含砂岩裂隙水等支护难点,提出了采用组合支护来提高巷道的初始支护强度等支护对策;通过对巷道载荷的计算并结合理论分析,确定了巷道的支护参数,数值模拟结果进一步验证了其良好的控制效果。工程应用结果表明巷道控制效果显著。

Control Mechanism and Supporting Technology of Roadway Surrounding Rock Under Complicated Conditions |

| Abstract: | Taking Zhangji Coal Mine 11418(W) mining roadway as engineering background,the existing support difficulties of larger change of roadway roof lithology and the existence of sandstone fissure water are analyzed.Combined support and the support measures for improving roadway's initial support strength are proposed.Through roadway's load calculation and theoretical analysis,the parameters of roadway are determined,and the numerical simulation results further verify the control effect.The engineering application results show that the control effect of roadway is remarkable. |
