| Abstract: | According to the problem exsiting in detecting the thickness of the coal seam, put forward the signal processing method for wavelet multiresolution analysis applying to analyzing the actual detecting signal. The processing results of the actual detecting signals indicate that the ability to identify the weak reflected wave is considerably improved and the accuracy to detect the thickness of the coal seam is increased. |
