Description

technical field [0001] The invention relates to the technical field of geophysical prospecting, in particular to a high-density resistivity measuring device powered by a large current. Background technique [0002] The measurement of resistivity and polarizability is an important means of geophysical exploration. This method can be applied to both metal ore exploration and environmental and engineering geophysical problems. It changes the exploration depth and horizontal position by changing the spatial relationship between the power supply and the measuring electrodes. [0003] In order to improve the exploration efficiency and data quality of this method, an automatic selection and switching device that arranges all electrodes in the working area at one time and connects them to the electrodes has been developed. During the measurement process, the power supply and measurement electrode selection are automatically realized through the acquisition program control. Enables ...
