The geological structure of the coalfield in Bigezhuang district of Fangezhuang Mine was complicated, and various small faults were developed, which had serious impact on production safety. With the development of seismic exploration technology and the improvement of mechanized production level of coal mines, the requirements for seismic data processing accuracy were becoming higher and higher, especially for small fault identification and prediction that affect production efficiency and safety. According to the structural characteristics of the coalfield in Bigezhuang District of Fanezhuang Mine, the seismic treatment method was preferred, which was especially important for the data processing effect and interpretation.
