摘　　要：为了实现废机油在现场混装乳化炸药中的资源化应用,优化某国外特大型矿山乳化炸药的成本结构,制备了废机油型乳化炸药,并从储存期、泵送、抗颠簸、爆速、殉爆距离及爆破块度分析等方面进行了基础性研究。结果表明:该废机油型乳化炸药具有良好的储存稳定性;符合泵送和长距离运输要求;爆速可以到达4 800 m/s以上;殉爆距离为15 cm;且矿山爆破效果良好,爆破后块度满足挖运要求。每吨乳化炸药油相成本可以节约23.32美元,具有一定的经济效益。In order to realize the resource application of waste engine oil in field mixed emulsified explosives, cost structure of emulsified explosives used in a super large mine aboard was optimized, and emulsion explosive containing waste engine oil was prepared. Basic research was carried out from the aspects of storage period, pumping, anti-bumping, detonation velocity, burst distance and fragmentation analysis. Results show that the emulsion explosive containing waste engine oil has good storage stability, meets the requirements of pumping and long-distance transportation, its detonation velocity can reach more than 4 800 m/s, and the burst distance is 15 cm. Blasting outcome is good, and fragmentation after blasting meets the requirements of excavation. The cost of oil phase per ton of emulsion explosive can be saved by 23.32 dollars, which has some economic benefits.
