Mathematical Optimization Models and Methods for Open Slope Design and Implementation in Open Pit Mines

In this thesis we study the open pit design problem the open pit mining scheduling problem and the open pit design problem with geological and price uncertainty These problems give rise to mixed discrete optimization models that in real life settings are large scale and computationally challengingThis article reminds the principles of slope design in open pit mines and presents techniques and tools available to address the successive stages of slope design Their practical implementation is then illustrated by two case studies of open pit min Corresponding author Tel 33 1 fax 33 1

Determining the Most Effective Factors on Open Pit Mine Open Pit Mining 911metallurgist

Abstract Determination of ultimate pit limit and sequence of blocks extraction through the mine life is referred as mine design and planning The aim of mine design and planning is to develop a yearly extraction plan which guides the mining operation to the highest Net Present Value NPV In model 1 with Stephen and in the previous topic we saw that the geological aspect is one of the main factors that affect the design of a surface mine What are the characteristics and other aspects should be taken into a code for the final configuration of the surface mine Between them we have to take into account of the safety economics and the recovery of the material
