Abstract：Based on years of monitoring data from dewatering wells water level in Chaoyang Open-pit Mine,this article systematically analyzes the dynamic variations law in dewatering wells water levels and the influencing factors,reveals the correlations between dewatering well water levels and factors including pit distance,stratigraphic structures and hydrogeological conditions,demonstrates the feasibility of postponing the third-phase dewatering well construction.Through stormwater runoff calculations and water treatment capacity assessments,we conduct a balance analysis between water supply and storage,propose the optimized scheme for comprehensive utilization of pit water,design water resource utilization system based on storage-drainage equilibrium,which provides a scientific basis for the efficient utilization of water resources and safe production in the open-pit mine.
