Abstract

Basedonthesuperpositionprincipleofseismicwaves,anewblastingvibrationwaveform predictionmodelwasproposedotherthanthetraditionalpredictionmethodsfoundedondatastatistics. Accordingtothemeasuredvibrationwaveformsfromsingleblastholes,thedevelopedmodel wasusedtocalculatetheblastingvibrationwaveformsatcertainlocations.Inthecalculation,theparameterswereconsideredasfollows: thepositionoftherecordingsiterelativetoeachblasthole,the delaytimebetweenthedetonationofeachtwoblastholeaccordingtotheactualinitiationnetworkand themeasuredpropagationvelocityofseismicwave.Thecalculatedresultsshowthatthedeveloped methodcanbeusedtopredicttheblastingvibrationvelocitypeaks,wholevibrationwaveform,vibrationdurationandmainfrequencydistribution. Andthecalculatedwaveformsarecoincidentwiththe recordedonesinthedeepholeblastingtestsusingelectronicdetonators.Itindicatesthatthedevelopedpredicationmethodisreliableforengineeringapplication.
