【摘要】 利用希尔伯特-黄变换(HHT)中经验模态分解(EMD)法,对武钢金山店铁矿微震监测信号进行分解,得到满足一定条件的IMF分量,再对其进行希尔伯特变换,得到能量谱图,通过对波形和谱图的分析,实现微震震源的提取及分类。更多还原

【Abstract】 Making use of EMD decomposition method in Hilbert-Huang transform,this paper decomposes the microseismic signals in Jinshandian Iron Mine of Wuhan Iron and Steel Corporation and obtains IMF components that meet certain conditions,which go through Hilbert conversion and yield energy spectrum.With analysis of the waveform and spectrum,it extracts and classifies microseimic sources in the very mine.更多还原
