It　is　necessary　to　study　the　dynamic　response　of　particles　under　blasting　excavation　to　ensure　the　safety　of　slope.　Based　on　field　blasting　vibration　monitoring　experiments,　the　wavelet　packet　transforms　and　numerical　calculations　were　used　jointly　to　study　the　energy　response　of　particles　in　a　slope　at　different　frequency　bands　and　the　dynamic　response　characteristics　of　key　positions　of　the　benches.　The　results　indicated　that　the　blasting　vibration　energy　in　a　rock　slope　would　change　in　different　frequency　bands.　The　energy　attenuation　and　amplification　effects　were　mainly　manifest　as　high-frequency　energy　attenuation　and　low-frequency　energy　amplification,　respectively.　The　peak　particle　velocity　(PPV),　energy,　and　peak　stress　of　the　slope　surface　are　generally　attenuated　with　the　increase　in　the　explosion　source　distance.　The　vibration　energy　in　the　51-100Hz　frequency　band　had　the　greatest　attenuation,　and　the　PPV　of　the　vertical　component　was　larger　than　that　of　the　horizontal　component.　As　the　elevation　increased,　the　vibration　energy　at　the　top　of　the　bench　had　the　largest　amplification　coefficient　in　the　11-25Hz　frequency　band.　Both　the　particle　stress　concentration　at　the　bottom　of　the　bench　and　the　＂whiplash　effect＂　of　the　PPV　at　the　top　of　the　bench　may　affect　the　stability　of　slope.　Thus,　the　safety　and　stability　of　rock　slopes　should　not　be　evaluated　by　only　considering　a　single　index,　but　it　should　be　combined　with　a　comprehensive　analysis　of　multiple　indices.
