High construction efficiency: large-area measurement can be completed quickly, and it has obvious advantages in coalfield hydrogeological exploration and other work.
Sensitive to low-resistance bodies: It has high sensitivity in finding low-resistance geological bodies in high-resistance surrounding rocks, such as effectively detecting coal mine goafs and water-bearing structures.
Strong anti-interference ability: pure secondary field observation is adopted, which is less disturbed by the primary field and has no terrain influence.
Good coupling effect: the same-point combined observation is best coupled with the detection target, with strong abnormal response, simple morphology and strong resolution ability.
Rich information: profile measurement and depth measurement can be completed at the same time, which can provide more underground geological information.
