According to the feature of the current channel wave seismic exploration and the development of mine seismic instrument, application of KDZ3113 mine seismic exploration instrument in mine was researched. The KDZ3113 is the latest generation of high speed, high resolution seismic exploration instrument in coal mine underground, which can apply to the exploration of geological structure by using variety methods of seismic work, like channel seismic, 2-D seismic, multi-channel transient rayleigh wave, and so on. Using the combined method of transmission and reflection, this instrument was applied to the 5316 work face in al mine of Shanxi. Meanwhile, by analyzing the data, 8 subsided columns and a fault were circled out, which further verify the practicability of KDZ3113 instrument for safety and efficient production in mine.
