Custom 2D Electrical Resistivity Tomography / Geophysical Resistivity System

2D Electrical Resistivity Tomography Geophysical Resistivity System

The mutil-electrode geophysical resistivity system used an array exploration method, also known as the automatic resistivity system. It is the development of the direct current method, which is equivalent to the combination of 4 poles vertical electrical sounding and electrical profile method. The artificial electric field is formed by electrode power supply to the underground, and the distribution of the electric field is closely related to the distribution of the resistivity of the underground geotechnical medium. By measuring the artificial electric field of different parts of the surface, the distribution of the visual resistivity of the underground medium is understood, and the underground geological structure is inferred and explained according to the distribution of the visual resistivity of the geotechnical medium.

2D Electrical Resistivity Tomography is particularly sensitive to the water content of surrounding rock. If the surrounding rock is broken, the apparent resistivity is significantly reduced, and the visual resistivity of complete and hard rock and soil is significantly higher than that of fault zone or fracture zone and water-rich zone. This method has clear principle and intuitive image, and is a geophysical exploration method with high resolution. In recent years, with the improvement of computer data acquisition technology, the exploration efficiency has been greatly improved, the coverage area and detection depth of the section have been increased, the reliable data can be obtained in the environment of strong interference, the signal-to-noise ratio has been greatly improved, and the geological body can be accurately detected. This method has been widely and successfully used in engineering and hydrogeological exploration and mineral and water resources exploration.
