摘　　要：立交巷道布置是矿井巷道掘进常用方法,合理的应力分析及支护设计是立交巷道施工的关键。以济宁三号煤矿立交巷道为背景,运用FLAC3D数值模拟软件对立交巷道围岩应力分布情况进行分析,提出合理的立交巷道支护设计方案,确保矿井安全生产。Interchange of roadway is a common method of mine roadway tunneling,reasonable stress analysis and support design are the key to the construction interchange of roadway. Based on the intersection of Jining No.3 coal mine, the stress distribution of surrounding rock was analyzed by using FLAC3Dnumerical simulation software, put forward a reasonable support design for the roadway and ensure mine safety production.

关 键 词：立交巷道 数值模拟 应力分布 支护设计
