Based on the hydrogeological data of the LiuJiagou minefield, the hydrogeological conditions of the minefield, source of water inrush and the water-filling channel were analyzed and studied. With the methods of big-shaft and catchment corridor , the mine inrush water was predicted. The result of catchment corridor method was more accurate, pre-mining area was 365.94 m3/h and minefield was 788.08 m3/h. It offered a scientific basis for prevention and control of water disasters of mine and production safety.
