摘　　要：为解决茂通煤业2^(#)煤层回风大巷支护的难题,综合运用矿压监测、实验室试验测试、数值模拟等手段,对其原有支护方案条件下矿压特征进行分析探讨,设计切槽嵌合卸压技术方案,采用FLAC^(3D)软件优化支护参数并验证可行性,在新掘巷段进行工业应用试验。结果表明,巷道变形量、锚杆受力在设计范围内,围岩整体稳定。In order to solve the support problem of the return air main roadway of the 2^(#)coal seam in Maotong Coal Industry,the mine pressure characteristics under the conditions of the original support scheme are analyzed and discussed by comprehensive use of the rock pressure monitoring,laboratory test,numerical simulation and other means,and the technical scheme of cutting and inlaying pressure relief is designed,the support parameters are optimized and the feasibility is verified by using FLAC^(3D) software,and the industrial application test is carried out in the newly excavated roadway section.The results show that the roadway deformation amount and bolt stress are within the design range,and the surrounding rock is stable as a whole.
