·Coal mining Underground Surface & Drilling The various methods of mining a coal seam can be classified under two headings surface mining and underground mining Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods and the choice of which method to use in extracting a coal seam
·The choice of whether coal will be mined by surface or underground techniques depends among other things on geological information and more specifically on the nature and thickness of the overburden The most important considerations in the selection of mining equipment can be grouped into the following categories mining conditions
This paper describes the ESP in the context of surface mining and discusses related problems and applications within the scope of both the ESP and related problems and outlines modeling and solution approaches One of the challenging problems for surface mining operation optimization is choosing the optimal truck and loader fleet We refer to this problem as the
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
