Hanxing coal mine area is a typical karst high-water deposit. With further exploration of under-group coal seams, various threats of water disasters came. Coal water disasters can be divided into five types through comprehensive study on geological and hydro-geological conditions of the coal mine area. The five kinds of water disasters are surfer water disaster, coal roof aquifer water disaster, coal floor high-pressure Ordovician karst water disaster, goaf water disaster and karst collapse column water disaster. For all types of water disasters, corresponding water control measures were proposed and these water control measures are of great theoretical and realistic significance to the mine safety and high-level decision in Hanxing coal mine area.
