Adjustment of operating routine in open pit mining given the coal market volatility

The economic efficiency of open pit mineral mining exhibits a tight connection and dependence on geological conditions, major open pit parameters, mining period and technology, method of operation, mechanization and management, as well as the selected operating routine. A routine of mining is a project-set sequence of stripping and actual mining in time to ensure safe, well-scheduled and economically efficient production. Operation of a coal mine is governed by the economic factors, first of all, which conform with the external macroeconomic conditions. A prime economic factor of mineral mining is the allowable mineral production cost composed of the operating cost of stripping and actual mining. At the known production capacity of an open pit mine, the cost of stripping depends in many ways on the stripping volume and conditions. Adjustment of the latter can change the mineral mining cost within certain limits, to ensure the mine profitability in the conditions of price volatility. The article discusses the operating routine adjustment in open pit mining subject to price volatility on the coal market. Controllability of the coal mining cost is estimated per mining stages connected with cycles of coal price fluctuations.
