摘　　要：采区高分辨率三维地震勘探是近两年用于煤矿达产采区，查清细微地质构造的新技术。数据处理是该项技术能否成功运用的重要环节。其技术关键是ＤＭＯ叠加代替常规共中心点叠加、叠前部分偏移加上叠后偏移代替叠前偏移、精细静校正与两步法子波反褶积、叠后高频补偿。结果表明：运用以上技术是获得高分辨率、高信噪比、高保真度三维数据体行之有效的方法。The high resolution 3 D seismic exploration in district is a new technique used in producing mine to find out the subtle geological structure in recent year and the data processing is the key link of this technique whether it is successfully applied or not.The main technology is using DMO stack to replace conventional CMP stack,using partial migration before stack with migration after stack to replace migration before stack,using accurate statics and two step deconvolution,and using high frequency compensation after stack.The results show that the above mentioned technique is the effective method to obtain high resolution,high signal/noise ratio,high fidelity 3 D data body
