High density electrical meterIt is a geophysical method that integrates electrical profiling, electrical depth measurement, and induced polarization method, and uses dense point spacing to conduct two-dimensional or three-dimensional electrical measurements. It has the advantages of high observation accuracy, large data volume, rich information, and faster measurement speed than electrical depth measurement.

　　High density electrical meterBased on the difference in conductivity between rocks and ores, a stable underground electric field is established by supplying a stable current to the ground. Using instruments to observe and measure the potential difference between electrodes on the ground, and then calculating the resistivity distribution of underground media based on Ohm's law, in order to infer the distribution of underground geological structures and geological bodies.

High density electrical meters are widely used in the following fields:

1. Exploration of solid mineral resources such as coal mines and metal mines: By detecting the resistivity distribution of underground media, the distribution and reserves of mineral resources can be inferred.

2. Engineering geological exploration: such as soil stratification, cave detection, foundation, pipeline and dam leakage detection, etc.

3. Hydrogeological exploration: such as groundwater distribution, environmental geological monitoring, groundwater pollution, etc.

4. Geological exploration of disasters: such as detection of bedrock interfaces, fault detection, landslides, goaf areas, etc.
