Principle And Advantages Of Electrical Geophysical Exploration

Electrical exploration is a geophysical exploration method to find ore and study geological structures according to the electrical differences of the electrical properties of rocks and ores, and is also a more widely used exploration method in the exploration industry. It is a widely used exploration method in the exploration industry. It is to observe artificial and natural electric fields or alternating electromagnetic fields through instruments, analyze and interpret the characteristics and laws of these fields to achieve the purpose of mineral exploration.

1 Resistivity testing technology for geotechnical bodies

Various methods can be used for testing the resistivity of geotechnical bodies. It plays a very important role for the current to dissipate into the earth as soon as possible, to achieve a small enough grounding resistance and the reasonable layout of the underground part of the grounding device, which is the main basis for the selection of grounding device type design.

2 Three-dimensional direct current method

Three-dimensional DC method of detection is the application of existing DC method instruments and exploration methods, construction methods to optimize the improvement, encrypted sampling data to obtain three-dimensional data body, and then take resistivity laminar imaging technology for data processing and mapping.

3 Multi electrode channels electrical resistivity method

Dozens or even hundreds of electrodes are arranged simultaneously on the pre-selected survey line and survey points; then they are connected to the special electrode conversion device by multi-core cable; the latter can be combined into the specified electrode device and electrode distance by the instrument's measurement program control according to the operator's instruction, and the resistivity observation of multiple electrode devices and multiple electrode distances on multiple survey points in the observation profile can be completed quickly. With the corresponding data processing, mapping and interpretation software, a given geological survey task can be completed in a timely manner.
