摘　　要：地质构造准确成像是煤矿地震勘探的关键。随着煤矿勘探程度的不断深入,地质条件越来越复杂,对地震成像的精度要求也越来越高。本文借助在新元矿区开展的三维地震资料二次处理项目,重点针对叠前时间偏移技术展开了深入研究。通过对各个技术环节的不断试验及对比分析,叠前时间偏移技术最终在矿区二次精细处理技术中取得了良好的效果。The key of successful seismic exploration is whether to image geological structure accurately. With the deepening of the coal mine exploration degree and more complicated geological conditions, the accuracy demand for seismic imaging is becoming higher and higher. This paper makes an in-depth study for Pre-stack time migration, with the aid of secondary 3-d seismic data processing program in a mining area of Xinyuan. In the end, the Post-stack migration technology has obtained the good effect in the secondary fine processing of mining area, through the test and comparative analysis of various technology link.
