摘　　要：针对程潮铁矿无底柱分段崩落法采场爆破,以弹性波波阻抗、岩石的坚固性、岩体的裂隙性、标准爆破漏斗体积时炸药的单耗作为分级指标,在程潮铁矿-375 m地段现场进行的一系列单孔爆破漏斗试验和跨孔声波测试,利用模糊识别理论对岩体可爆性进行模糊综合评价。Aiming at suhlevel caving stope in Chengchao-lron Mine, we establish the blasting evaluation method which is based on the role of the energy balance and makes elastic wave impedance, the solid rock, rock fissures, unit consumption of standard blasting explosives be as a classification criterion, by the way iron a series of single-hole blasting funnel tests and the cross-hole acoustic test in - 375 m place of Chengchao-Iron Mine, and use fuzzy identification theory of fuzzy math to evaluate hazily the rock blasting.
