| 摘 要： | 地震波超前探查是目前较为先进的超前地质预报技术,但准确度一直备受质疑,通过实际研究表明:地震超前探查的准确度取决于速度的选取,实际处理中由于初次采取的速度是建立在以往地面三维地震勘探的基础上,其速度选取有一定误差,造成断层解释的不准确性。而扫描速度谱与偏移速度建模相结合的方法,对初选取的速度参数进行修正,重新处理得到的结果与实际揭露结果吻合。结果表明:通过扫描速度谱与偏移速度建模相结合的方法选取速度参数,对于提高煤矿巷道地震超前探查构造的准确性具有重要意义。

| Abstract: | Advanced detection of seismic waves is more advanced geologic prediction technique at present, however, the accuracy is a controversial issue, the research results show that the accuracy of advanced detection of seismic waves depends on the speed selection, because the first time to adopt speed is built on three-dimensional seismic survey, speed selection has certain error, lead to inaccurate interpretation of the fault. Through the combination of scanning speed spectrum and migration velocity modeling, the second processing corrects the parameters of the speed according to the first processing, the results coincide with the actual results. Therefore, adopting the correction parameters of the speed becomes particularly important for improving the accuracy of seismic exploration according to the combination of scanning speed spectrum and migration velocity modeling. |
