Research and application on 3D seismic exploration technology of coalfield in especially complex area
At present,3D seismic technology in general areas has become a common technical means in the field of coal exploration,pro-viding a favorable technical guarantee for the investigation of coal resources and safe and efficient mining of coal mines.However,in are-as 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.
