Prominent coal and groundwater are a rare type of prominent disasters in coal mines. Since 1961, the coal seam C_ (13) in the second mining area of Huai Nan Kongji coal mine has occurred successively in the direction of 250m in length and 150m in height, five times in succession, with a maximum of 1119m ~ 3 coal and a maximum of 340m ~ 3 / h.
