摘要
根据榆树井煤矿水文地质条件,对顶板淋水巷道围岩控制技术进行研究,针对顺槽控制难点,提出了顶板锚网索耦合支护、两帮高强锚杆+不对称锚索+喷浆支护、底板反底拱+锚网(梯)索+喷浆支护的巷道围岩控制技术,并设计了临时支护及永久支护方案。现场监测效果显示围岩变形在可控范围内。
According to the hydrogeological conditions of Yushujing Coal Mine,research is conducted on the control technology of the surrounding rock of the roof watering roadway.In view of the difficulties in the control of the groove,the control technology of the roadway surrounding rock is proposed,including the coupling support of the roof anchor mesh cable,the two side high-strength anchor rod+asymmetric anchor cable+shotcrete support,the bottom plate reverse arch+anchor mesh(ladder)cable+shotcrete support,and temporary and permanent support schemes are designed.The on-site monitoring effect shows that the deformation of the surrounding rock is within a controllable range.
