Abstract: Seismic model technology is a model experimental method and seldom used in coalfield exploration and coal mining at present. In order to realizing precisely survey under coal-seam geological condition， seismic model might be used to simulate complex geological phenomena， analyze all kinds of disturbing wave on the basis of basic principles and experimental method of seismic model. Velocity and frequency of main secondary disturbing wave might be obtained by this model. It provided a good way for filtering disturbing waves from field actual seismic data.
