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...
ramp-up in a new mine is important in generating early revenue and pay back on investment (and a significant advantage of SLC as a top down mining method). While a fast ramp-up is desirable, the time required for this should not be underestimated.
1 de dic. de 2019 · For most cases, 20% of the time is considered for ramp-up, 60% of the time for the steady state, and 20% for ramp-down, although it is necessary to make adjustments in extreme conditions (high or low production rates and reserves).
Nezhadshahmohammad et al. (2018) presented a multi-index clustering approach to decrease the solution time in order to optimize the sequence of the extraction using the MILP method.
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.
An empirical method based on the relational study between various parameters is used to outline the key criteria to be used in the optimization of drawpoint loading in block caving.
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.
