Based on a brief introduction of hydrogeological conditions, three well exploiting plans were primarily selected such as gallery, radial well and seepage well. In order to calculate the reasonable exploiting yield, the concept of equivalent permeability coefficient was used to construct the model of coupled seepage and pipe flow. The reasonable exploiting yield of gallery, radial well and seepage well are 149000,0and 287000cubic meter per day.The simulation results suggested that the water supply of seepage well is higher than that of gallery or radial well and has high guarantee rate in the same technology condition. Seepage wall is chosen as the best exploiting plan to get a high water efficiency, which has very importment significant for the reasonable exploitation of groundwater in this region.
