Equipment Selection for Surface Mining A Review
productivity. In surface mining applications, the ESP addresses the selection of equipment to extract and haul mined material, including both waste and ore, over the lifetime of the mining pit. In this paper, we focus speci cally on the truck and loader equipment selection problem for surface mines.
CHAPTER 11 Mining Technology Princeton
Surface Mining Techniques Surface mining of coal is characterized by the use of large, capital-intensive and effi-cient mining equipment. First, the overlying soil and rock layers (overburden) are re-moved. The coal is then fractured with explo-sives or machines, and loaded onto vehi-cles for haulage from the mine site. Finally,
Selection Of Mining Machinery
Equipment Selection for Surface Mining A Review. The type of loader selected for use in a surface mine depends on the type of mineral to be extracted and speci cations of the environment such as the bench height. We must also consider other factors in the equipment selection process particularly the compatibility of the loaders with .
An MILP approach to multilocation multiperiod equipment
In the surface mining industry, the Equipment Selection Problem involves choosing an appropriate fleet of trucks and loaders such that the long-term mine plan can be satisfied. An important characteristic for multi-location (multi-location and multi-dumpsite) mines is that the underlying problem is a multi-commodity flow problem. The problem is therefore at least as difficult as the fixed ...
