To　study　the　surface　particle　vibration　of　vibration　wave　propagation　on　slope　casting　blast,　we　utilize　dimensional　analysis　to　construct　the　vibration　peak　velocity　formula　including　the　factor　of　elevation.　On　the　basis　of　the　above　theory　and　slope　casting　blast　model,　we　divide　a　blasthole　charge　into　sumless　micro-units　for　integral　operation,　and　eventually　obtain　the　formula　of　particle　vibration　peak　velocity　on　slope　casting　blast.　The　results　show　that　under　the　same　condition　of　geographical　environment　and　blasting　technology,　peak　velocity　primarily　depends　on　explosive　performance,　charge　depth,　monitoring　point,　explosion　source　space　and　blasting　acting　index.　We　obtain　a　series　of　peak　velocity　on　explosion　site,　and　put　the　measured　data　at　the　slope　surface　and　in　the　slope　body　into　the　Saudorsky　formula,　the　average　errors　between　the　predicted　peak　velocity　values　by　the　formulas　and　the　measured　values　at　the　slope　surface　are　32%,　34.25%,　29.58%,　39%　and　7%,　respectively.　The　average　errors　between　the　predicted　peak　velocity　values　by　the　formulas　and　the　measured　values　in　the　slope　body　are　27.63%,　23.5%,　16.88%,　33.889%　and　13.25%,　respectively.　©　2019,　Editorial　Staff　of　EXPLOSION　AND　SHOCK　WAVES.　All　right　reserved.
