15 de ene. de 2016 · The ramp-up time for a project in mining and mineral industry is dependent upon a number of factors, including: Process complexity. Metallurgical sensitivity to processing parameters. Ore...
Portal to Steady State – Effectively evaluating project goals using SimMine® mining simulation software. Mine development, ramp-up, and production require significant investment. Optimised resource planning and scheduling of underground mining can prove to be extremely valuable by ensuring the project is completed on time and within budget.
25 de may. de 2023 · Abstract. Sublevel shrinkage (SLSh) is an underground mining method similar to sublevel caving (SLC) but with continuous backfilling from the top. It features a top-down mining sequence with production drifts orientated in a longitudinal or transverse way in the orebody.

This measure is conceptually a useful way to assess productivity as it is relevant for all stages of the mine’s production cycle (ramp-up, steady state and ramp-down) and can be compared across operations of all sizes.
1 de ene. de 2015 · open access. Abstract. Ramps (or declines) are often used in underground mines to transport ore, waste, materials, and personnel. This paper studies mine ramp productivity and presents results from a set of computer simulations designed to model the fundamental behaviours of ramp haulage systems.
