In order to solve the problems of low resolution and poor detection accuracy of current mine seismic exploration instruments, this paper used the data acquisition station of the 24-bit £-ΔA/D converter and the NetBEUI LAN signal transmission protocol to design and develop a synchronization based on the principle of electromagnetic induction. The instrument is a new generation of high-speed, high-resolution mine seismic equipment, and may be applied to geological structure exploration of coal underground channel wave seismic, underground two-dimensional seismic, transient multi-point Rayleigh wave and other seismic work methods. This paper used this instrument to carry out a joint exploration test of channel wave transmission and reflection on a mining face, and through analysis of the collected data, a total of 8 faults and 1 collapse column were delineated, which were confirmed in the later mining face and further verify the accuracy and practicability of the instrument in the safe and efficient mining of coal mines.
