Using the remote control low-density electrical method system through borrowed wires, it changes the traditional high-density electrode layout method to solve the problems of shallow exploration depth and large blind spots in traditional high-density electrical exploration. It is a new conceptual method for electrical exploration that can be used with traditional high-density electrical instruments. The power electrodes AB are placed at both ends of the measurement area, and the receiving electrodes MN are placed in the middle of the measurement area. With the minimum variation of electrode combinations, the most effective resistivity data can be obtained, greatly improving the measurement depth of traditional high-density electrical instruments. It can effectively measure high-precision data within a depth of 800 meters and has obtained multiple patented technologies.
By quickly carrying out central gradient, joint quadrupole sounding, etc., people can solve some 2D/3D exploration needs at small and large depths
The yellow represents the designed underground curtain wall, which adopts a three-dimensional dragon-shaped array to expand the effective range and increase the depth of inversion. It is several times more effective than the three-dimensional snake-shaped high-density inversion.
The red is the survey line coordinate axis X, direction from west to east; black is the vertical survey line coordinate axis Y, direction south to north; blue is the elevation coordinate axis Z, direction from bottom to top, and the color mark on the left is the ground contour scale. The gray surface is the 500Ωm isosurface, and the resistivity in the enclosed area is greater than 500Ωm; the purple surface is the 300Ωm isosurface, and the resistivity in the enclosed area is less than 300Ωm; the three-dimensional resistivity image shows the distribution of low-resistance areas, with an altitude of 2760m and shallower than the north and south. There are low-resistivity anomalies in the direction, which is inferred to be an underground river or karst development zone; no low-resistivity anomaly is found below an altitude of 2750m, and it is inferred that the deep karst development is weak. Drilling and interwell electromagnetic wave CT were arranged to verify the 3D array resistivity results.
