摘　　要：以王楼煤矿13301工作面的地质条件为工程背景,综合分析了条带膏体充填开采技术,并利用FLAC3D数值仿真软件,建立了承压水上条带膏体充填开采的流-固耦合数值模型,证明条带膏体充填开采可以有效地防治13301工作面底板突水的发生,最终经现场实测测得工作面底板最大破坏深度约为10.25 m,与数值模拟所得结果基本吻合。The geological conditions of 13301 working face in Wanglou coal mine as engineering background,a comprehensive analysis of the strip filling mining technology,and using FLAC^3D numerical simulation software,built on the confined water with paste filling mining fluid solid coupling numerical the model,that strip filling mining can effectively prevent water inrush in13301working face floor occurrence,by in-situ measured working face floor maximum damage the depth is about 10.25m,consistent with the results of numerical simulation.
