Abstract: in order to search an effective suppression mnethod and procedure of the multiple waves in coafeld and improve the integraed image quaity of coal-tearing basin by seismi: information,with model data as a guide and in combination with thelogging data an analysis was conducted on multiple wave features included inthe tvo dimension seismi data of a mine in ner Mongolia and in combination wth the mutiole wave suppression method,an experiment was conducted on the adaplabilty The resuts showed that before the pre-stack,the Radon Filtlr method was aplid to the attenuation of the long distance mutile waves and afer the post-stack.he prediction mninus method based on the wave eqcuaton was aplied to the suppression of short distance mutiple waves with a well image effect obtained.Therefore inorder to liminate the rmutiple waves affected to the tectonic inage.the methods to be appid should be thathe icentification and clssfication should be frstly condtcted on the mutiole waves included in the data,then acording to the different type mutiple wave featues n combination with advantages and disacvantages ofthe suppression method before pre-stack and afer the post-stack.the slitstep identifcation and classification would be the effective accss o have the high qualtyseismiccross section.
