     The main aim prospecting Huanghe reservoir Nantun finds preliminarily the underground caves and geology in the region through geophysical methods,provide the necessary reference for the assessment of geological disasters in the region.It is relatively good results to find the IP intermediate gradient,IP combined profile and apparent resistivity sounding through the experiment of various geophysical methods.The groundwater is developed,and there is water in the known collapse positions,water conducts electricity well.Therefore,the apparent resistivity is lower when the Surface measurement.When the caves without groundwater,the apparent resistivity shows high resistivity anomaly.It can find the underground caves according to the apparent resistivity values.
