Abstract: At present,Qixiashan lead zinc mine has been mined to the middle section of -725 m,and the hydrogeological conditions have changed to some extent.In order to prevent water inrush accidents in the mine,the mining enterprises have formed a set of relatively perfect water control system from many aspects,such as the formulation of water control system documents,the strengthening of hydrogeological investigation and research,the improvement of hydrogeological drawings and accounts,and the establishment of drainage system with the required capacity.Practical application shows that the system plays an important role in checking the geological conditions of Qingshui and preventing water inrush accidents in mines.
