The design and implementation of Magnetic Resonance Sounding system for shallow groundwater exploration

The existing Magnetic Resonance Sounding (MRS) system for groundwater exploration can detect the deep groundwater, transmit a high power, and hold a large size and weight. Due to the conditions of transportation and instrument preparation time, the work efficiency of the existing system has not obvious advantage to detect the widespread shallow groundwater. In view of the characteristics, a way to constitute MRS system for shallow groundwater exploration is reported in this paper. The main factors which influence the magnetic resonance detection ability are analyzed and the technical specifications of the key part are defined. On the basis of that, a portable MRS system for shallow groundwater exploration is developed. As compared with JLMRS-I system developed by Jilin University, the portable MRS system for shallow groundwater exploration showed the same inversion results. The shallow groundwater detection efficiency is remarkably improved due to the swift and portable instrument.
