摘要(Abstract)：

根据声波反射法探测顶煤厚度中存在的问题,提出了将小波多尺度分析应用到实际煤厚探测信号分析中的信号处理方法。结果表明:小波多尺度分析大大改善了煤层顶板弱反射波的识别能力,提高了煤厚探测的精度。
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.
