Abstract

Drill rig availability is essential in the mining industry's value chain. Ensuring transparency and traceability in the performance of the drill rig availability is critical. The purpose of this study is to evaluate the effectiveness of the drill rig availability rate based on maintenance compliance, mean time to repair, and mean time to failure. The studies were carried out using literature analysis and other scientific methodology including Pareto charts. A capability analysis was undertaken by collecting data on weekly planned maintenance, daily mean time to repair of drill rigs, and mean time to failure of drill rigs. The goal of using the analytical tool was to check the central tendencies of the data and process variation. This analytical tool also helped us identify what level each process is at in terms of sigma. A cause-and-effect diagram and failure mode and effect analysis were used to conduct a more in-depth root cause investigation. The goal of the cause-and-effect diagram was to examine the elements that contributed to the poor drill rig availability, including service and mean time to repair (MTTR). The FMEA was used to assess the effectiveness of the present controls for process failure and to define new actions to close all process gaps. Recommendations have been made to bridge the gaps with the most significant contributors to the low drill rig availability. This study collects data using the case study methodology. The contribution of the study is based on the assessments have been done to the mining industry that has not been addressed by current literature.
