基于SCT槽波数据处理软件的频谱与频散分析研究

Study on spectrum and dispersion analysis based on SCT slot wave data processing software

为了提高槽波勘探的准确度,压制干扰波以及其他无用波,提高信噪比,得到相速度以及群速度频散曲线,更好地反映研究区域特点以及研究区地质构造,采用SCT槽波数据处理软件,对槽波地震波频谱与频散进行研究和分析。研究得出:通过对频谱分析,能量大部分集中在一个频率范围(50~350 Hz)内,说明该工作面大部分槽波频率在50~350 Hz;对频散分析,在利用槽波SCT槽波数据处理软件时,应当尽可能对频散曲线进行拾取,从而保证有充足的数据进行分析,以提高槽波勘探的准确度,研究为煤矿勘探层析成像技术提供一定的技术支持。

In order to improve the accuracy of slot wave exploration,suppress the interference wave and other unwanted waves,improve the signal to noise ratio and get the phase velocity and the group velocity dispersion curve,better reflect the regional characteristics of the study area and the geological structure of the study area,using SCT slot wave data（ 50 ~ 350 Hz）,which is based on the spectrum analysis. Most of the energy is concentrated in one frequency range（ 50 ~ 350 Hz）,which shows that most of the troughs of the working surface are analyzed by analyzing the spectrum and dispersion of the trough wave seismic wave. Frequency in the range of 50 ~ 350 Hz;for the dispersion analysis,in the use of slot wave SCT slot data processing software,should be as much as possible to pick up the dispersion curve,so as to ensure sufficient data to analyze,to improve the groove wave exploration accuracy,research for coal mine exploration tomography technology to provide some technical support.
