摘　　要：巷道围岩松动圈的大小影响着巷道的变形及施工人员的人身安全。对煤矿而言,收集某一采区的松动圈实测值,对相似采区巷道的采掘有很好的指导意义。采用探地雷达测定王楼煤矿15121轨道顺槽围岩松动圈的大小,应用FLAC3D软件模拟验证,分析了探地雷达用于探测巷道围岩松动圈的科学性,预测了松动圈的发展,很好地应用于指导支护参数的优化。The magnitude of the fractural rock ring affects the deformation of roadways and the safety of workers working there. As far as the coalmine is concerned, the collection of a series of data in fractural rock rings is meaningful to the roadway excavation in similar conditions of mining areas. The authors measured the data of fractural rock ring in No. 15121 track gate, and made the numerical simulation by means of the FLAC^3D software. This paper analyzes the feasibility of detecting the fractural rock ring with the help of the ground penetrating radar and forecasts the development of fractural rock ring. As a result, it can optimize the design of support parameters.
