| Abstract: | It is possible to predict coal seam thickness with trace integration method,but the type and dominant frequency of wavelet have an effect on the calculated coal seam thickness.The accuracy of predicted coal seam thickness can be improved by choosing the proper filtering bandwidth in accordance with the distribution range of coal seam thickness and filtering the trace integration sections. |

| Keywords: | trace integration method thickness inversion frequency filtering inversion accuracy |
