Abstract: The changes of thickness consequentially bring the changes of seismic wave field attribute parameter,therefore,for reference abstraction seismic attributes technology is used in the course of exploration.At the same time introduce wavelet transform instrument,abstracting wavelet field attribute parameter in different frequency bands,and utilize BP neural network technology proceed the aggregate prediction of the multiparameter thickness of coal seam.By real data verification,the technology is feasible and the forecast with the result is less than 10% of differ.
