In surface mining, equipment selection problem involves choosing a fleet of trucks and loaders that have the capacity to move the materials specified in the mine plan within a stipulated period. The optimization problem is to select these fleets in such a way that the overall cost of materials han dling is reduce.
Surface mining a broad egory of mining in which soil and rock overlying the mineral deposit (the overburden) are removed. mountaintop removal mining a large scale form of coal mining in which entire mountaintops are leveled strip mining a method of mining that is used when a mineral is near the surface and underground passages are not needed

select the optimal mining method based on production, cost and environmental criteria. The cost and production model for both the conventional and SM mining methods consider a mediumsize surface coal mine in WV. For this study, the mediumsize mine is deﬁned with a production rate of million bank m3 of overburden to be excavated annually
Underground mining (hard rock) Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals such as those containing metals like gold, copper, zinc, nickel and lead or gems such as diamonds. In contrast soft rock mining refers to excavation of softer minerals such as coal, or oil sands.
