摘要
系统地研究了南芬露天铁矿电铲、电动轮汽车和牙轮钻机的作业时间．得出了它们的固有可用度和实际可用度，提出了影响各设备实际可用度的因素，同时得出电铲的作业时间和故障时间服从威尔布分布。
The production periods of excavators, trucks and drillers of Nanfen Surface Iron Mine are systematically studied in this paper. Their theoretical and practical availability and some factors affecting the practical availability are obtained. The no -failure time and failure time of excavators are Weibull distributed.
