摘　　要：以屯兰矿18205工作面沿空留巷为工程背景,详细介绍了巷内的基本支护方式、加强支护与巷旁支护设计。采用FLAC3D数值模拟分析了掘进、留巷,一直到留巷复用各阶段的巷道变形数据,总结出了巷道变形的基本规律,并对各个阶段巷道的变形情况给出了合理的支护意见。Taking the gob - side entry retaining in 18205 working face of Tunlan Coal Mine as engineering background, the paper introduces basic support in roadway, strengthening support and roadside supporting design in detail. FLAC3D numerical simulation is used to analyze the monitoring data of deformation during various stages from driving, retaining to reusing. By numerical simulation, the fundamental principles of roadway deformation are summarized, which provides rational explanation and supporting suggestions for different stages deformation.
