In order to be more scientific, detailed and accurate to analyze the complex geological structure of the mining area of 3 d seismic results, and according to the study area in the basic geological background, 3 d seismic data were dealt with the synthetic seismogram calibration, time slice analysis, and the geologic model correction was used, integrated use of model test, the results showed that to adopt the appropriate offset in combination with the actual can be a very good exploration result of complex tectonic zone.
