Abstract
Single-stage hoisting from ultra-deep level mining operations is vital for
sustainable exploitation of mineral deposits beyond current depths( <3000m).
Analysis of options available to hoist men, material, and ore takes the form of
industry visits, the study of cases, proposed and new ideas. Operational feasibility
is done by the analysis of the methods available. Underground mineral
processing is discussed with a view to combining it with other available
hoisting methods and taking advantage of likely spin-offs. New materials for
ropes, conveyances and pumping accessories, and other options are
discussed.
Power consumption and consequently unit cost of the same is used
extensively in evaluating the possible transportation scenarios.
Skip hoisting with a revised factor of safety regulations and new rope materials
is still an attractive option so is the concept of hydraulic hoisting of fine
material with a centrifugal pump. Rope-less technology is still futuristic for all
practical intent
