摘要
分别从钻机与后续挖掘机作业能力匹配及炮孔负担爆破量角度分析了钻机效率,并分别确定了钻机效率计算公式,确定了矿岩硬度、钻机风压及钻具质量是影响钻机效率的重要因素,并从减小钻机外障影响时间、提高维修效率及提高操作人员熟练程度等方面提出了提高钻机效率的措施。
The article analyzes drilling rig efficiency from drilling rig and subsequent excavator operation capability match and blasthole burden blasting yield, and determines calculation formula of drilling rig efficiency, the important factors of affecting drilling rig efficiency, such as ore and rock hardness, drilling rig wind pressure and drilling rig quality. It presents the measures of improving drilling rig efficiency from reducing the drilling rig waiting time, improving repair efficiency and enhancing the skilled degree of personnel aspects.
