Small-scale mining faces many challenges, such as the proportionally higher costs related to mineral exploration, the time for the results associated with these activities to become available and the difficulties to dispose of waste throughout the mine life. This paper considers three innovative approaches to address small-scale mining issues: appl...

Underground mining is a highly competitive industry that is often singularly focused on material production as a key performance indicator. However, maximizing material production does not always maximize industry profitability. Equipment utilization in support of underground mining operations is a significant factor that affects both material prod...

Small-scale mining usually operates under high geological uncertainty conditions. This turns mine planning into a complex and sometimes inaccurate task, resulting in low productivity and substantial variability in the quantity and quality of the mineral products. This research demonstrates how the application of a novel methodology that relies on t...

The strategic mine plan is a crucial step for the success of mining companies, and for its development, it is necessary to use a number of inter-related variables that are usually estimated independently. These variables include operational data that is traditionally isolated in information islands between the different departments in the mine or t...
