摘要

旋转钻机是采矿和建筑施工中最常用的爆破钻孔机械。钻井作业在采矿活动中的重要作用表明，对钻井机械的性能分析及其故障和维修行为至关重要。因此，本研究的重点是钻机的可靠性、可用性和可维护性。本文以伊朗Sarcheshmeh铜矿的4台旋转钻机为研究对象，进行了维修和故障数据采集。采用马尔可夫方法对钻床的随机存储器进行了分析。结果表明，每小时钻井，钻井机队的可靠性降低0.67%。液压系统是所有机器不可用的主要原因。此外，两台最新机器的大部分故障都在25小时内完全修复

RAM analysis of rotary drilling machines

Rotary drilling machines are the most common machines used for drilling the blast holes in mining and constructions activities. The vital role of drilling operation in mining activities reveals that, the performance analysis of drilling machines and their failure and repair behaviors are essential. There-fore, the present study focuses on the reliability, availability and maintainability (RAM) of drilling ma-chines. In this paper, four rotary drilling machines at Sarcheshmeh Copper Mine in Iran are considered for repair and failure data collection. RAM analysis of drilling machines is done using Markov Approach. Results show that the reliability of drilling fleet is decreased by 0.67% in per hour drilling. The hydraulic system is the main unavailability reason of all machines. Moreover, the most failures of the two newest machines are completely repaired in 25 hours
