Abstract：The hydrogeological conditions of Yingping phosphate mining area in Fuquan City were analyzed through the method of analysis and further study. The water-rich areas, where faults, joints and fissures developed near the south wind shaft project, were selected, and the hydrostatic pressure, water level, filling diameter and drainage of underground water were intervened to investigate the recharge funnel formed by pumping and draining and to ascertain the main causes and approaches of water invasion by the deep excavation project. The results show that the drainage of large-caliber boreholes in the water-rich areas with developed faults and joints can achieve the draining effect, which could solve the water invasion hazard and be considered as an effective measure. The prevention and control method has great promoting significance in the construction of similar mines in the region.
