露天矿工艺系统可靠性对露天矿的主要技术经济指标有很大影响，特别是采用连续或半连续开采工艺时更是如此。故应在设计及生产管理等各个阶段，重视提高工艺系统的可靠性。本文依据国内外露天矿的经验，从理论与实践相结合的角度，对提高露天矿工艺系统可靠性的途径进行了综合分析。 The reliability of the open pit process system has a significant impact on the major technical and economic indicators of the open pit mine, especially when using continuous or semi-continuous mining processes. It should be in the design and production management and other stages, emphasis on improving the reliability of the process system. Based on the experience of open-pit mines at home and abroad, this paper analyzes the ways to improve the reliability of the open-mines technology system from the perspective of the combination of theory and practice.
