Abstract

Accordingtotheblastingexperiencesandactualexplosion-in-rockinducedrockfragmentation, theshockwaveenergyproducedbytheliquidexplosiveexplosionwasseparatedintothesurface energyofthefracturedrockandthestrainenergyintherockbyapplyingtheenergyconservationlaw. Andbasedontherockfracturemechanicsprinciple,amodelwasproposedtopredicatethefragmented rockparticlesizesinthecrackedregion.Acalculationexamplewasgiveninwhichthediameterofthe fragmentedrockparticleswas1.43mm.Thecalculatedresultsdisplaythatthediameterofthefragmentedrockparticlegeneratedbytheliquidexplosiveexplosioninrockisequivalentt thatofthehydraulicfracturingproppantparticleintheoilindustry.
