Abstract

Water inrush from the mine roof greatly threats mine safety. In this paper, in order to predict whether a roof water inrush accident will occur during the mining process, we considered the inclined water-resisting roof layer of mine as a rectangular thin plate with four clamped edges, and obtained critical water inrush criterion based on the principle of minimum potential energy and Mohr–Coulomb yield criterion, in which the linear increasing water pressure and the supporting force of fractured rock mass were considered. For a specific project, the stability of water-resisting layer was analyzed by Flac3D based on the fluid structure interaction method, and then the effectiveness of critical water inrush criterion was verified. These results provide valuable guidance for the prevention of water inrush from roof of working face under similar geological conditions.
