ABSTRACT

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. Decrease of the current stripping ratio will allow, at each mining phase at the bottom of the open pit mine up to a certain depth, to form a cut trench with dimensions corresponding to the contour of the ore shoot. It becomes possible, without significant additional costs, to pass the advance initial cut to the maximum contour of the open pit field by reducing the width of the open pit edges to a depth corresponding to the optimum height of the rock mass rise by dump trucks. Afterwards, the first line of the lifting conveyor can be positioned in a stationary position from the surface until the end of the open-pit mining of the mineral occurrence reserves.

Keywords: open pit mining, steeply dipping mineral occurrences, combined automobile-conveyor transport, advance initial cut, conveyor lift.
