摘要
介绍了小波变换的基本概念及其特性,通过对模拟岩石断层信号的小波处理,提取其频谱特性,从而确定岩石内部的完整性,了解断层结构所对应的波谱特性,为确定岩石的内部结构,了解岩石的内部状况作好预知性工作,为矿山开发等实际生产应用起到参考借鉴作用。通过对岩石断层结构在信号的前三个尺度上的反映,根据样本岩石的结构来确定波谱特征,实践证明该方法十分有效。
Concept and characteristics of wavelet transformation are described in this paper. The integrated feature of rock and the feature of wave pedigree are defined by extracting its frequency pedigree feature and treating simulate rock integrated single with wavelet. It can be a good preliminary to the definition of the inter-structure of the rock and the understanding of the inter-state of the rock. It can also be a complementary reference for the exploitation of mine and other practice or production. This essay defines the feature of wave pedigree of the rock structure by the rock integrateds responses on its signals first three dimensions and the structure of the rock sample. Practice has proved that the way is very effective.
