Implementation of many investment projects connected with large mineral deposits across Russia is essentially impeded by under-developed transport and public infrastructure, inefficient decisionmaking risks and insufficient case study of strategic scenarios of mining process and mine development. New mining projects in Russia involve integrated optimization of mine planning and design in difficult geological and geotechnical conditions. The correct strategy and optimized technology selected for the mining process can ensure sustainability of a mine for a long time. This article describes an authors’ approach to designing a quarry and selecting a mining system. The optimized and effective development strategy is presented as the case-study of Mokulaevskoe limestone deposit. Alternatives of pit wall parameters and structure are presented as 3D visualization of northern Mokulaevsky site. The calculation data on work content and transport infrastructure parameters depending on the chosen mining system are given. The change in the stripping ratio as a function of the mining advance alternative is described. The advantages and disadvantages of the mining advance scenarios are defined. The approach to the design decision-making is assessed. The sound design of the pit wall working zone and the optimized strategy of mining advance in difficult geological and geotechnical conditions make it possible to ensure higher productivity of mining and handling machines, to reduce stripping ratio and to enhance mining efficiency.
