本文讨论了露天煤矿连续工艺系统可靠性的计算方法。据此可更正确地估计出系统的年有效工作小时数,从而为轮斗铲系统中设备规格的选取提供依据。针对元宝山露天煤矿连续工艺系统所作计算表明,对该矿选择的轮斗铲规格提出了改进建议。 This article discusses the method of calculating the reliability of a continuous process system for an open pit mine. Based on this, the annual effective working hours of the system can be more accurately estimated, which provides the basis for the selection of equipment specifications in the wheel bucket shovel system. The calculation for the continuous process system of the Yuanbaoshan Opencast Coal Mine shows that some suggestions for improving the specifications of the shovel shovel chosen by this mine are proposed.
