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 in a mine in Huaibei is extremely complex with small faults developed well and the dip of local coal seam is large. Conventional 3D seismic prospecting has been unable to meet the requirements for the interpretation of small faults in production. Based on the analysis of the geological data of the mine, the observing system was designed in a targeted way. Finally, by comparing with the conventional 3D seismic prospecting data in this area, it is considered that the digital high-density 3D seismic exploration has a great advantage in explaining the small structure It is of practical significance to guide coal production.
