摘　　要：淮北某矿34采区构造极为复杂,小断层十分发育,且局部煤层倾角大,常规三维地震勘探已无法满足生产中对小断层解释精度的要求。在对该矿地质资料分析的基础上,有针对性地设计了观测系统,最后通过与该区常规三维地震勘探资料的对比,认为全数字高密度三维地震勘探在解释小构造上有较大优势,对指导煤矿生产具有现实意义。The structure of 34 mining area is very complex in a mine of Huaibei, small faults are well developed, and local seam dip angle is too large, conventional 3D seismic exploration has been unable to meet the requirement which needs high-precision in the interpretation of small fault in production. Based on the analysis of the mine geological data, the targeted observation system was designed. Compared with conventional 3D seismic data, the interpretation of small structure based on the all digital high density 3D seismic data has great advantages, which is of realistic significance to guide the production of coal mine.
