Abstract:
Sublevel caving is considered the most efficient method for underground mining of ore deposits; however, its loss and dilution rates vary significantly between sites. This variability is traditionally assumed to be due to differences in the design parameters of the mining unit. This study, based on an analysis of mining operations, found that design parameters (spacing between sublevels, working width, and drilling and blasting parameters) have no statistically significant relationship with recovery rates. In contrast, geological parameters explain over 60% of the dilution variability. Based on this, three types of deposits with different expected performance indicators were identified. The obtained results indicate the dominant role of geological factors and require a rethinking of the design methodology for sublevel caving systems.
Keywords:
sublevel caving, losses and dilution, design parameters, development system, completeness of extraction
