Business activities in the mining industry are associated with significant uncertainty, as well as with the specific and market risks, which can be reduced in open pit mining at the stages of design, planning and operational management. The specific and market risks, characterized by dynamic behavior, require adequate technical, economic and technological solutions. The hierarchical levels of management in the nature-and-industry system during field development are presented, the hierarchized scheme of impacts is offered, the essence of the external and internal influences at different levels of management is analyzed, and the corrective responses are justified. The hierarchical levels of management of the natural and technological system include: the investment environment, the nature-and-technology system, the mining plant, the stage of development, the technological zone of the quarry, the natureand-technology zone and the extraction block. At each level the essence of disturbing influences divided into external and internal is revealed. It is noted that in case of low-frequency changes in the price of mineral products, it is essential to assess the current position of the price cycle, which should be constantly monitored to make informed decisions on the adjustment of the parameters of ore flows and the financial and economic situation. The key to the sustainable operation of the mining and processing plant in the downward branch of the price cycle is the possibility of using technological, technical, organizational and financial leverage for an adequate response to external disturbance.
