摘　　要：为研究开采深度对沿空掘巷围岩变形规律的影响,运用FLAC3D数值计算,建立了沿空掘巷数值计算模型,从巷道围岩应力分布、巷道围岩塑性区分布和巷道围岩表面位移分布3个方面分析了不同开采深度下沿空掘巷围岩变形规律,并成功指导了工程实践。In order to study on mining depths impact on roadway driving along next goal deformation law of surrounding rock, using of FLAC3D numerical calculation and establishing numerical calculation modal of roadway driving along next goaf, from the surrounding rock stress distribution, the distribution of plastic zone and the surrounding rock roadway surface displacement distribution of three aspects analysis different mining depths roadway driving along next goal deformation law of surrounding rock, and successfully guided the conclusion of the project practice.
