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...
Evaluating the mine design for the build-up phase into two years of steady-state, the model shows the target advance and tonnes are achievable and follows the ramp-up strategy to achieve steady-state.
30 de abr. de 2017 · The principles of the middle-and long-term production planning for the block caving at Tongkuangyu mine, the optimization of drawing control under the overlying rock, the numerical method for the...
Open pit mine planning is a decision-making process that leads to a realistic and actionable plan to profitably extract mineral resources. Planning can be carried out for a wide range of periods from the very short (next shift) to the very long (life of mine) (Whittle, 2011).
1 de ene. de 2015 · 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.
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.
25 de may. de 2023 · 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.
