A regulation of the mining operations mode during a new phase of open pit mining deep lying minerals through implementation of temporary non-operating open pit edges on many deep open pit mines made it difficult to extract minerals. Innovative technologies of working zones development along steep open pit edges have been tested at the pre-design stage with comparison of the obtained mining schedules with the design schedules based on the analysis of methods of controlling mining operations mode and their existing ...

A switch to combined automobile-conveyor transport is offered, i.e. cyclical and continuous method, at an early stage of the development of steeply falling deposits, based on usage of advantages of the safe intensive development of working zones along the steep open pit edges at a number of open pit mines on the territory of Kazakhstan. It is possible to shift from traditional approaches of cutting a new pit banks by advance of the cut trench with the minimum dimensions on the round-shaped open-pit fields. Decreas...
