Optimization of Design Parameters and Intelligent Back-analysis of High Bench Dump Slope in Open Pit
Dump engineering is an important part in production processes of open-pit mining. In order to complete the mine production tasks smoothly, it is necessary to make the most of land possessed by the dump in an economical and reasonable way. In the paper, we use the dump of Qidashan iron mine which belongs to Anshan Iron and Steel Group as an engineering background to achieve the aim of improving ...
متن کاملA new developed model to determine waste dump site selection in open pit mines: An approach to minimize haul road construction cost
Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displacing by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main w...
متن کاملSimulation of Groundwater Fluxes during Open-pit Filling and under Steady State Pit Lake Conditions
A critical component in determining post-mining pit water quality is knowledge of groundwater fluxes, both as the pit fills and after steady state conditions have been reached. Simulations of the filling of an open pit in Crescent Valley, Nevada, were made to generate inputs for pit lake chemistry predictions. The simulations show that the water table recovery is most rapid immediately after pu...
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 کاملDetermination 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...
