Abstract

Developed in 2015, the long-term strategy for the Muruntau and Myutenbai deposits, with validation of quality standards and re-appraisal of the reserves in 2016, provides stage-wise advance of mining. The initial stage operations are to be carried out within the limits of phase IV (up to 2019). Then goes a transition period for completing extraction of phase IV reserves (2020–2028) and continuing expansion of the open pit mine within the limits governed by preservation of the available surface infrastructure and cyclical-and-continuous method conveyors (2020–2034) in order to ensure construction of an inclined shaft with conveyor lines from the northwest pit wall Muruntau to Hydrometallurgical Works 2 (2033–2039) and with regard to ultimate limits reached by the pit wall benches (by 2036–2037). Later on, between 2035 and 2050, mining will be implemented within the limits of phase V. Meanwhile the required mining and transport equipment is to be reliably estimated with regard to available conveyor systems involved in the cyclical-and-continuous technology. The calculations of the number of dump trucks and shovels, accomplished with sufficient accuracy and multi-factor analysis, allow planning overburden and ore haulage with respect to the operating conveyor lines of the cyclical-and-continuous technology at the joint Muruntau–Myutenbai open pit mine for a period up to 2040. It is also taken into account that starting from 2039–2040, the inclined conveying shaft towards Hydrometallurgical Works 2 will start operation on the western pit wall while the eastward high-angle conveyor (KNK-270) and the crushing-and-loading point (DPP-3500) will be dismantled.
