Reliability, Maintainability, and Availability of Mining Drilling
Drilling represents the initial and most crucial phase in open pit mining operations that utilize the drilling and blasting method. The mobility of all drilling machineries, facilitated by the undercarriage moving between drilling sites, is essential. Any malfunction in this system can hinder movement and, ultimately, halt drilling activities. The reliability, maintainability, and …
