High-slope　and　rock　mass　joint　development　are　the　factors　for　predicting　and　controlling　blasting　vibrations　under　open　pit　mining.　Blasting　vibration　adversely　affects　the　stability　of　jointed　rock　slopes,　thus　studying　the　characteristics　of　blasting　vibration　frequency　bands　in　jointed　rock　masses　slope　is　an　important　task　to　ensure　the　safety　of　blasting　operations.　In　the　present　study,　vibratory　ground　motions　were　measured　during　blasting　excavation　in　open-pit　mining,　and　the　blasting　vibration　frequency　band　characteristics　of　jointed　rock　masses　and　high　slope　were　studied　through　the　wavelet　transform　and　response　spectrum　method.　The　results　demonstrated　that　the　amplification　effects　of　the　peak　particle　velocity　(PPV)　and　energy　between　different　frequency　bands　exhibited　distinguishing　characteristics.　It　was　found　that,　with　the　increase　in　elevation,　the　PPV　and　energy　amplification　effects　were　the　most　obvious　in　the　0-16　Hz　band,　while　they　were　attenuated　in　the　32-64　Hz　band.　Furthermore,　the　distribution　of　dominant　frequency　bands　of　vibration　signals　observed　to　be　low　and　narrow,　and　the　average　frequency　had　been　reduced.　In　the　development　of　joints　in　rock　masses,　the　PPV　and　energy　in　each　frequency　band　were　attenuated,　and　the　distribution　of　the　dominant　frequency　bands　of　vibration　signals　was　high　and　wide.　Also,　the　average　frequency　had　been　increased　and　the　multi-modal　characteristics　of　the　responses　to　blasting　vibrations　were　more　obvious.　The　rock　mass　structures　had　displayed　different　amplification　effects　on　the　frequency　components　of　the　blasting　seismic　waves.　Finally,　as　the　effects　of　jointed　rock　masses　on　the　blasting　load　responses　could　not　be　simply　considered　as　reducing　vibrations,　they　must　be　analyzed　using　vibration　theory　and　actual　situations.
