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

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