Based on the shallow buried coal seam working face strong pressure problems existing in the process of mining, a typical shallow buried coal seam working face conducted mine pressure law observation. According to the result of mine pressure observation appeared in shallow seam, mining pressure regularity and characteristics were analyzed. The basic laws of roof movement and its motion parameters, tip-to-face roof slice of risk were mastered and the stent rationality was studied.
