In order to find out the range of mined-out area within 200 m around the mine field in the next 3 to 5 years in Jinrui Mine, this paper optimized the data acquisition of ground-air electromagnetic method based on the ground-air electromagnetic detection method, aiming at the problems of low exploration degree in the periphery of the mine field, large mining time span of ancient small kilns and complex and changeable spatial form of water accumulation area. The research formed a high signal-to-noise ratio and high-precision ground-to-air electromagnetic detection data acquisition method suitable for the detection of water disasters in old kilns in complex terrain areas, with the core technical support of fine management and control of key layers and optimal allocation of frequency points and sorties. The results showed that the technology greatly improved the detection and identification accuracy of the old kiln water, and realized the accurate identification and characterization of the hidden disaster-causing factors of the ancient small kilns around the production mine.
