Determination of the largest pit with the non-negative net profit in the open pit mines
The determination of the Ultimate Pit Limit (UPL) is the first step in the open pit mine planning process. In this stage that parts of the mineral deposit that are economic to mine are determined. There are several mathematical, heuristic and meta-heuristic algorithms to determine UPL. The optimization criterion in these algorithms is maximization of the total profit whilst satisfying...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

متن کاملOpen pit limit optimization using dijkstra’s algorithm
In open-pit mine planning, the design of the most profitable ultimate pit limit is a prerequisite to developing a feasible mining sequence. Currently, the design of an ultimate pit is achieved through a computer program in most mining companies. The extraction of minerals in open mining methods needs a lot of capital investment, which may take several decades. Before the extraction, the p...
متن کاملA Proposed Biological Survey of the Berkeley Pit Lake System
Very little is known about the organisms that are impacted by mine waste in the Berkeley Pit Lake System. However, it is known that if heterotrophic and autotrophic organisms are properly nutrified, they can bioremediate mine waste-influenced areas as a benefit of their physiological processes. However, before any type of bioremediation of an ecosystem can begin, it is essential to gain a funda...
