Abstract:Scientific and effective evaluation of groundwater resources is the key to sustainable development of groundwater resources, and the evaluation of exploitable groundwater resources is the core content of groundwater resources evaluation. Based on detailed analysis of hydrogeological conditions and karst collapse development of Xiaogongzhuang water source area in Taierzhuang district of Zaozhuang city, the allowable exploitation of karst groundwater in Xiaogongzhuang water source area is calculated by using mining test method. The calculation result is 11354m3/d. According to already happened karst collapse, the early warning water level of karst collapse has been set. The safe mining yield has been calculated by Theis formula. The unsteady flow is 11187~13150m3/d. The calculation results have been evaluated furtherly by using mining test method. According to the evaluation results, it is determined that the allowable exploitation rate of Xiaogongzhuang water source area is reliable. It can ensure the maximum exploitation of groundwater resources in the water source area, and ensure that the environmental geological problems of karst collapse are not easily caused when the water source area runs. This method provides some references for the calculation and evaluation of groundwater allowable exploitation in the same type of water source area.
