Abstract: On the basis of summarizing the seismic geological conditions of Huaibei mining area, this paper analyzes the reasons for the application deficiency of conventional 3D seismic exploration the area. Through elaboration of the characteristics of all digital high density 3D seismic exploration technology, this paper proves the advantages of the technology in the structure exploration and lithology exploration in Huaibei mining area with multiple cases. Finally it points out the development direction of the technology in the coalfield seismic exploration and states the application prospect of the technology.
