Impact of criticality analysis on the operational availability of Scooptrams LH203 in the Huarochirí Mining Industry

Abstrak

This study addresses the decline in the operational availability of low-profile loading equipment used in underground mining, a challenge primarily attributed to shortcomings in the implementation of preventive maintenance strategies. The main objective is to propose a preventive maintenance model based on criticality analysis aimed at improving the availability and operational efficiency of such equipment. Adopting a quantitative approach with a non-experimental, cross-sectional design, the research applies a descriptive method to assess the impact of the maintenance plan on equipment availability, using operational and maintenance data collection and analysis. The results reveal a significant increase in equipment availability from 79.20% to 92.57% following the implementation of the model. This highlights the relevance of maintenance strategies grounded in criticality analysis and real-time monitoring technologies. The findings underscore the success of the proposed model in enhancing both availability and operational efficiency, and demonstrate its potential for replication in other mining sectors to promote safer and more efficient operations.
