摘　　要：随着煤矿开采深度的增加,厚油页岩顶板地质条件下的巷道支护问题日益凸显。针对这一问题,对煤矿厚油页岩顶板的地质特性进行了深入分析,并通过理论计算确定了巷道顶板围岩松动圈的范围,为支护参数的确定提供了科学依据,还确定了锚杆和锚索的支护参数,并建立了数值模型以进一步优化锚杆和锚索的间排距参数,旨在提高支护效果并达到降本增效的目的。研究结果表明,优化后的锚网索支护方案能够更有效地控制巷道围岩的变形和破坏,提高巷道的稳定性和安全性,研究成果不仅为厚油页岩顶板地质条件下的巷道支护提供了科学依据,也为类似地质条件下的巷道支护设计提供了借鉴和参考。With the increasing depth of coal mining,the issue of the roadway support under conditions of thick oil shale roof is increasingly imperative.The geologic characteristics of thick oil shale roof of a coal mine is analyzed,and the range of surrounding rock’s loos circle of roadway roof is determined by theoretical calculation,providing scientific basis for the determination of support parameters.The support parameters of anchor rod and anchor cable are also figured out,and a numerical model is built for further optimization of the spacing parameters of anchor rod and anchor cable in order to improve the support effect,reduce cost and boost efficiency.The results show that after the optimization,the deformation and failure of roadway’s surrounding rock is effectively controlled,and its stability and safety is enhanced.The study not only provides scientific basis for roadway support under conditions of thick oil shale roof,but also offers reference for roadway support with the similar geological conditions.
