Abstract：We detail how to interpret minor faults in coal seams by using pattern recognition technique,including fuzzy multiparameter decision,fuzzy pattern recognition,fuzzy clustering analysis,linear pattern recognition and fuzzy segment linear patterr recognition.Characteristic parameters of seismic wave mechanics(including amplitude,frequency,phase and curvature of waveform),fuzzy theory and pattern recognition technique are applied to structure interpretation of seismic data.Consequently,many minor faults(the throw is about 5m)in two prospects were newly discoverect by reinterpreting the processed seismic data,some of the minor faults have beer confirmed by geological data in coal mining,thus resulting in satisfactory geologica effect.
