摘　　要：对大冶铁矿大理岩和原生矿体的钻孔指标进行监测，建立合理单耗与钻进速度关系式。观测数据建立在多年参数优化与成本模型计算的基础上，利用该式来指导生产能使爆破参数选取合理、作业成本降低，且不需专门的试验。Through monitoring and measuring of drilling indices of marble and primary ore body of Daye Iron Mine, a rational relationship between unit energy consumption and drilling speed is established. The observed data are based on the optimization and model calculation of parameters of many years. According to the relationship, rational choice of blasting parameters can be achieved, reducing operation cost and eliminating special tests.
