露天矿设备选择时,对设备的生产能力、完好率、可维修性等指标的要求愈益严格。系统的复杂性已发展到这种程度,已经在孕育“可靠性工程学”来满足日益增长的技术要求。本文将简述可靠性的某些基本观点,并指出如何运用这些观点来研究各种主要露天矿设备及其部件的完好率。引言露天矿系统由于较高的生产能力、安全性以及增长的人班效率而受到欢迎。它是一个机械化系统,运出千百万吨矿岩,消耗巨 Opencast mining equipment selection, the equipment capacity, good rate, maintainability and other indicators of the increasingly stringent requirements. The complexity of the system has grown to such an extent that “reliability engineering” has been nurtured to meet the growing technical requirements. This article will outline some of the basic concepts of reliability and point out how to use these ideas to study the integrity of various major open pit equipment and their components. Introduction Opencast mining systems are welcomed due to their higher productivity, safety and increased productivity. It is a mechanized system that carries millions of tons of ore and consumes huge amounts
