Abstract: In order to make clear the mechanism and control status of coal floor water bursting accidents in North China coal mines, we collected hydrogeological information from multiple mines in North China, studied the hydrogeological conditions of North China coal mines from mine water enrichment coefficient and water inflow, understood waterproof protective equipment, personnel and management status of coal mines in north China, analyzed the mechanism and main reasons of the larger water bursting accidents from years of 2012 to 2015. All these provide information base of waterproof and water conservancy in North China coal mines.
