Abstract Seismic attributes technology is now widely used in seismic prospecting engineering.In this paper,the authors used seismic attributes technology to predict the coal seam thickness in Longdong loess tableland,obtained the seismic prospecting field data in the prospecting area and extracted a variety of seismic attributes from the coal seam reflected wave.Based on the correlation analysis of the known coal seam thickness and the seismic attributes,the authors found that the coal seam thickness has a good linear correlation with seismic spectral attribute.The authors took advantage of the center frequency and amplitude attribute of the seismic attribute to predict the coal seam thickness in the whole prospecting area.The variation trend of coal seam thickness agrees with the coal seam thickness in drill hole,which indicates that coal seam has frequency tuning function and it is feasible to predict the coal seam thickness with the seismic spectral attribute.
