Abstract: Based on the existing geological data in Zhangwan well field and through field survey and theoretical analysis and demonstration, a feasible technical scheme adapted to the seismic geological conditions in this area is worked out to carry out 3D seismic exploration technology with high precision in Zhangwan area so as to further investigate the structure and coal seam occurrence of this section in detail. The geological and geophysical results provided by seismic exploration method can help to solve the problem of large borehole network in the exploration area, find out the more complex geological structure in the area, delineate the occurrence range of coal seam, and provide geological basis for the determination of the scope of early mining section in Zhangwan mine field.
