Abstract

Waveletanalysisandindependentcomponentanalysis(ICA)wereintegrallyappliedtoinvestigatetheseparationofthemeasuredshort- delayblastingvibrationsignalsintwodrillingholes. Waveletanalysiswasusedtofilteroutthehigh-frequencysignalwithalowerenergyratiointheblastingvibrationsignalsandtoextractthereconstructedsignalsinthefrequencyrangwiththem infeatures. ThereconstructedsignalswereseparatedusingICA.Thesegmentalseismicwavesweresuccessfullyobtained, whichcouldreflectthepracticalsituation.Andtheactualshort-delayintervaltime ofthesegmentalseismicwaveswasdetermined.ItisindicatedthatICAishelpfulforblastingvibrationsignalprocessing.
