Shandong Energy Zibo Mining Group Corporation Tangkou Mine westen F area was provided with complex structure，plenty of large fault, fold development, large coal seam inclination, tremendously thick magmatic rock shielding on coal seam and large variaration of coal seam depth placing. Normal three-dimensional post-stack immigration was conducted, though whole visage of this area was reflected, the imaging effect was not good and cannot meet needs. Kirchhoff pre-stack time immigration was applied to  conduct three-dimensional seismic data. Contrasive analysis showed that  pre-stack time immigration achievement preceded normal treatment in construction and energy information. Data volume conducted by pre-stack time immigration got clear imaging fault， accurate homing，reliable and meticulous geology form.
