| Taking Hui Ze lead-zinc mine Kuang Shan and Qi Lin area as the research object, many times we went down to the mine tunnels and climbed on the surface of tne mountain for hydrogeotology survey, gathering the water sample, doing hydrochemistry and isotope analyses, mapped the piper diagram and isotope rainfall line profile, It provides a scientific foundation for classifying groundwater aquifer types, determining the hydraulic connection of groundwater and doing water seepage dynamics research. On the basis of predecessors’ information collection, this paper analysis the 1584,1031 and 1764 section gushing water data in recent years to make a water inflow trend analysis, and using the gray theory method to establish the grey forecasting model of mine water. According to mine hydrogeological conditions and the relevant data, GMS software 3 d geological model is established to simulate the flow field and water gushing prediction. The results show that: with the exploit of the mine, the surface water gradually has a direct hydraulic connection with the deep karst water, surface water and deep karst water are mixing more and more frequently, central carbonate karst aquifer hydraulic activity is more relevant closely.Grey prediction forecasts the water inflow is 188.3 m~3/h and 1031 is 38.5m~3/h in the year of 2016. Two section water gushing trend decrease gradually, in current situation, the mine water gushing situation is relatively stable. GMS software is used to simulate groundwater seepage at Kuang Shan mine, the influence of drain Well is larger in simulation, the whole seepage fields are stable relatively, and forecasts the water inflow is 198 m~3/h in the year of 2016. |
