According to the data in the exploration and development of coal, petroleum and coalbed methane, and based on an analysis of the growth history of the Sitou fault, its sealing mechanisms are studied in respect of juxtaposition, clay smear, cataclasis, and cementation. The mylonite resulted from strong cataclasis can act as a seal of the coals. The cementation resulted from underground water activity is of great significance to the sealing ability of the fault. Mylonitic coal layers resulted from faulting occur on both sides of the fault.
