As a result of the drastic reduction of shallow mineral resources, the exploitable potential and reserve of proven mines are insufficient, and the mineral resources in deep ground need to be more refinedly explored.There are some disadvantages of the existing instruments, such as few channels and slow sampling rate, etc. Therefore, multi-parameter transient electromagnetic instrument with synchronous receiving has been developed and tested. The instrument is composed of two controllers, embedded controller and programmable logic controller, which can provide diversified information combination. Under the grounding electrode source emission mode, the real-time synchronous transient electromagnetic acquisition system of six channels is achieved with 128 k sampling rate. The data of the six channels are recorded in the full time range in the time domain. At the same time, experiments were carried out in laboratory, open areas and actual mine. Through data analysis, the measured data curves of the mining area are highly consistent with the existing geochemical exploration curves and geological profile.
