This　paper　classifies　the　blastability　of　fractured　rock　mass　based　on　the　solid　coefficient,　rock　impedance,　unit　explosive　consumption　and　mean　fracture　spacing.　Specifically,　an　evaluation　model　was　established　according　to　the　principle　of　clustering　analysis,　and　applied　to　classify　the　rock　mass　blastability　of　an　actual　project.　According　to　the　field　acoustic　test,　the　average　longitudinal　wave　velocity　of　the　layered　rock　mass　is　2,667m/s,　and　that　of　the　intact　rock　mass　is　3,346m/s.　Through　the　evaluation　of　blastability,　it　is　concluded　that　the　layered　rock　mass　has　a　high　blastability　while　the　intact　rock　mass　has　a　medium　blastability.　The　findings　lay　an　important　theoretical　basis　for　blasting　parameters　optimization　and　field　blasting　test.　Copyright　©　2017,　AIDIC　Servizi　S.r.l.
