outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is ...

Operations + Maintenance = Production -

The maintenance cost for this pulp mill is $87 per ton or a total of $43.5 million per year. A 5 percent reduction in maintenance costs would be worth $2.175 million/year, or 24 percent of the value of increased and sold production. In this example, it should be obvious that your joint operations/maintenance focus should be reliability.

Types of Maintenance -

A Maintenance Model is a mixture of the previous types of maintenance in certain proportions, and it responds appropriately to the needs of a particular equipment. We think that every equipment will need a different mix of different types of maintenance, a particular mix of tasks, so that maintenance models will be as many as existing equipment.

What types of plant are found on mining operations?
