Abstract: Seismic facies analysis technique has become a new technology of coal lithology seismic exploration. This paper expounded the seismic facies analysis method based on waveform classification, classified different waveform through artificial neural network detection technology to classify different waveform to achieve the purpose of distinguishing different targets. Respectively using the methods to delineate the scope of igneous rocks, to predict washing-thinned belt of coal seam and to identify fault, collapsed column and other geological anomalies as examples, the effectiveness of the seismic facies analysis technology in the field of seismic exploration for the lithology of coal field was discussed.
