The objective of these efforts is to determine the most profitable excavation plan and the highest rate of return on investment. These tasks are performed in the field of long-term planning.Using the Whittle software for strategic planning and optimization of excavation boundary and software Gems for construction the open pits, the long-term directions of exploitation the lead and zinc ore deposits in the Brskovo ore field are defined depending on the flotation processing capacity, quality of mineral raw material in terms of useful and harmful components. and making the maximum profits in that production process.
