高阶相干技术在煤田断层检测中的应用

高阶相干体算法在抑制噪声的能力和减小计算量方面优势显著。将高阶统计量方法与相干体技术相结合,提出了一种基于高阶统计量的相干体计算的新算法——高阶相干技术,并将高阶相干技术应用在煤田断层检测中。实践证明,高阶相干技术相对于常规相干技术能够更好地解释断层,且具有速度快、误差小的特点。 

Application of high order coherence technique in the fault detection in coal field

As Chinese coal geology conditions are complicated, the mine disasters are frequent.Majority of water inrushes in mine floor have the direct relation with faults.Therefore, to find out the size and distribution of faults is one of the main targets in seismic survey.High order coherence algorithm combines the higher-order statistical method with coherence cube technology from the view of enhancing the ability to suppress noises and to reduce the amount of computing points.A new algorithm to compute coherent bodies on the basis of higher-order statistical amount was introduced.High order coherence technique has been applied in real fault detection in the coal fields and achieved good results.
