摘　　要：目前一般地区三维地震技术在煤田勘探领域已经成为了常用的技术手段,对于煤资源的调查和煤矿安全高效开采提供了有利的技术保障。但是在地表地形变化剧烈,地下煤层构造复杂的地区,地震勘探的效果往往不佳,尤其是采集的单炮质量和处理的技术手段等方面还有待提高。甘肃赤城区地形起伏剧烈,沟谷纵横,煤层倾角个别地方达到了50°,属于特别复杂地区。以赤城煤矿为例,介绍了三维地震从设计到处理过程的关键技术,对于类似地区开展三维地震勘探工作具有借鉴意义。At present,3D seismic technology in general areas has become a common technical means in the field of coal exploration,providing a favorable technical guarantee for the investigation of coal resources and safe and efficient mining of coal mines.However,in areas where the surface topography changes sharply and the underground coal seam structure is complex,the effect of seismic exploration is often poor,especially the quality of single shot acquisition and the technical means of processing need to be improved.The terrain in Chicheng District,Gansu Province is highly undulating,with crisscrossing valleys and coal seam dip angles reaching up to 50 degrees in some areas,making it a particularly complex area.Taking Chicheng Coal Mine as an example,this paper introduced the key technology of 3D seismic from design to processing,with reference significance for 3D seismic exploration in similar areas.
