Study on Influencing Factors and Planning Model of Mining Quantity About Mineral Resources in Open Pit

According to the particularity of the open pit, the main influencing factors of mining quantity about mineral resources have been summarized systematically in life cycle, and the structured hierarchical relation of its influencing factors has been constructed. In the light of the production process of open pit, the functional relationships between investment, mining cost, and mining quantity have been defined based on the process of mining and loading so that the relation of the life-cycle cost and mining quantity can be set up. And what’s more, in order to obtain the maximum economic profit of mining enterprises in life cycle, the planning model of mining quantity has been established based on the life-cycle cost. The rational distribution of mining quantity is found on the condition of obtaining optimal solution about the planning model so as to determine scientifically the production scale of mining enterprises from the point of view of the sustainable development.
