In order to solve the problem of the strong ore pressure in the mining process of a shallow buried coal seam working face, the ore pressure law of a shallow buried coal seam working face was observed. According to the observation results of ore pressure, the law and characteristics of ore pressure on the working face of shallow buried coal seam are analyzed, the basic law and parameters of roof movement and the roof plate falling situation on the end face on the working face are obtained, and the rationality of the support is studied.
