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
期刊介绍：
Mining Scince. Scientific Papers of the Department Geoengineering, Mining and Geology of the Wroclaw University of Technology. The journal publishes original papers on mining and geology, geo-engineering and the related issues. The journal is devoted to the following topics: fundamental research in mining, underground and open-cast mining technologies, blasting technology, design and construction of mines, geomechanics and geotechnical engineering, mine ventilation, fluid mechanics and its application in mining, mining machinery and condition monitoring, mineral processing, environmental protection and waste utilization. The journal also accepts papers concerns geoengineering which is a sciences covering mining construction, geotechnical engineering, GIS, and earth sciences.
