Electrical Resistivity Survey Method Instrument Groundwater Exploration Device VES Vertical Electrical Sounding Survey Resistivity method is a group of electrical exploration methods based on the resistivity difference of rocks and ores in the earth's crust to observe and study the variation and distribution law of artificial electric field, and then to carry out ore prospecting, solve structural, hydrological and engineering geological problems, and carry out environmental monitoring. Symmetrical quadrupole sounding is a kind of resistivity method, which uses four electrodes a, m, N and B
A power supply circuit is formed to measure the apparent depth of strata by changing the electrode spacing symmetrically
Resistivity method. Through the analysis of the measured data combined with the geological conditions, the facies is made
