A Standardized Time Classification Framework for Mobile Equipment in Surface Mining: Operational Definitions, Time Usage Model, and Key Performance Indicators

This guideline provides a classification framework for operational activity that will enable meaningful performance analysis and industry-wide comparison. The framework includes the following:

• Recommendations for the consistent classification of common surface mining operational activities, statuses, and events into standard time categories.
• A Time Usage Model, which is a visual representation of the recommended classification framework identified above.
• Recommended definitions for common industry operational key performance indicators (KPIs) for reporting mining asset availability and utilization.
• The time categories, Time Usage Model, and KPI definitions outlined in this guideline are not intended to be industry standards; these are recommendations for recording and understanding operational performance. The framework documented in this guideline will support further collaboration aimed at developing additional KPIs and definitions.
