摘要:
针对露天高台阶抛掷爆破对炸药品种、性能的技术要求，优化设计了抛掷爆破炸药关键组分乳胶基质的生产工艺和配方。采用低温、低转速、敞口式连续乳化技术，水相温度为75℃，析晶点为60℃，pH值为3.9，复合油相温度50℃；乳胶基质中水的质量分数达22%，密度为1.42g/cm3，粘度为20~24 Pa?s（温度为65~72℃），无雷管感度，具有较好的稳定性、流动性和本质安全性。研发了重乳化炸药、重铵油炸药和超低密度炸药的配方。采用多功能混装炸药车生产工艺，可以在同一炮孔中不间断装填多个品种炸药，也可以在同一炮孔中连续装填不同型号的重铵油炸药，生产效率高达750 kg/min。经过现场抛掷爆破验证，新配方炸药爆炸性能稳定，满足抛掷爆破对炸药性能的要求。
Abstract:
The manufacture process and formulation of the critical component-emulsion matrix for the casting blast explosives were optimized according to the technical requirements in species and performance for high-step application in openpit mine. Using low temperature, low speed and open type continuous emulsification technique which enables water temperature of 75 ℃, crystallization point of 60 ℃, pH value of 3.9 and the oil phase temperature of 50 ℃, the emulsion matrix was fabricated with a water content of 22%, a density of 1.42g/cm3 and a viscosity of 20 to 24 Pa?s (at 65~72 ℃). It shows non detonator sensitivity and good stability, liquidity and safety. The formulations of H-ANFO, heavy emulsion explosive and ultra-low-density explosive were also developed. By multiplefunction mixed explosive truck, a varieties of explosives or different types of H-ANFO could be continuous loaded in the same borehole. The production efficiency could be up to 750kg/min. It was proved by onsite casting blast test that the new explosives were stable and could meet the demands for casting blast. 
