Assessment of efficiency of transition to a new wave of technological innovation in underground mining during is continuous progression to deeper levels

A new wave of technological innovation in an underground mine involves state-ofthe art control of mineral quality using high-velocity belt-type separators to remove the bulk of waste right at the stage of mining. This enables pushing the mine project limits and allows extraction of noneconomic low-grade ore reserves. Being very attractive, the in-situ separation technology to be introduced in mines needs that separated waste is handled, which is possible by means of combining separation with the technology of cemented backfill preparation using mobile modular-type backfill plants. The implemented research included the comparative economic analysis of the ground-level and underground location alternatives of the backfill prep plants at the same flow charts of rock haulage and hoist. The economic and mathematical model is developed for the assessment of the ground-level and underground locations of backfill prep plants. The underground location appears to be more preferable. Efficiency of transition to a new wave of technological innovation in underground mining continuously progressing to deeper levels is quantitatively assessed.

Keywords: new wave of technological innovation, ore quality control, underground mining, in-situ separation, high-velocity belt-type separators, cemented backfill, mobile backfill preparation plant, waste handling, economical and mathematical modeling, ore haulage and hoist cost reduction.
