Abstract

Aimedatthefollowingcharacteristicsoftheexplosionexcitationseismicwaveincarbonate rockswhichincluding weakenergy,highfrequencyandlowsignal-to-noiseratio,anon-coupling chargecoefficientoftheseismicsourcewasdefinedtoimprovethehole-chargestructure.Calculation modelswereproposedforexplosionloadandtransmittedwaveenergy,andthecorrespondinganalyticalsolutionswerecalculatedbyprogramminginMATLAB. Andthen,thefieldexperimentationwas conductedandtheexperimentaldatawereanalyzedbyusingtheenergyanalysismethodbasedonpowerspectra. Boththetheoreticalcalculationandthefieldexperimentationshowthatthetotaltransmittedwaveenergyissmallerwhenthenon- couplingchargecoefficientisbigger,butthemainfrequency oftheseismicwaveislowerandthesignal-to-noiseratioisthehighestwhenthenon-couplingcoefficientis1.5.
