Dual-lane multi-electrode electrofluoroscopy detection system

Abstract

A two-tunnel multi-electrode electrical penetration and detection system comprises: two electrode cables (11), each being provided with multiple sets of electrodes, and each set having multiple electrodes; an electrical instrument (12), for measuring a potential value between electrodes in corresponding sets on the two electrode cables (11); and multiple cable connecting lines (13), for electrically connecting the electrode cables (11) and the electrical instrument (12). The two-tunnel multi-electrode electrical penetration and detection system can collect a potential value between two adjacent electrodes in the same tunnel, and can also collect a potential value between the two tunnels. By using the potential values, a plane position relative to the water abundant area in the working plane can be positioned from multiple dimensions, and the positioning accuracy is improved.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a double-lane multi-electrode electrofluoroscopy detection system. Background technique [0002] The mine face is often threatened by groundwater during mining. Especially mines with complex hydrogeological conditions are often threatened by mine water inrush, so it is necessary to detect the occurrence of groundwater and eliminate water damage. At present, the detection of water damage in the mine working face adopts the method of combining geophysical prospecting and drilling. Usually, the geophysical prospecting is carried out first, and then the drilling is used for verification to ensure the safe production of the mine. The working methods that can be used to detect the water-rich area of ​​the mine working face by the direct current method include the high-density resistivity method and the direct current perspective method. [0003] The mine high-density resistivity method is cur...
