Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978. Surface mining is used to produce most of the coal in the because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.
The Equipment Cost Calculator is an online, interactive version of the Mine Mill Equipment Estimator''s Guide that allows you to change the parameters for calculating hourly costs, such as repair labor, diesel fuel, gasoline, natural gas, electricity and lubricants. This Calculator will allow equipment estimates in locales outside North America.
Coal prices at surface mines are generally lower than prices at underground mines. In locations where coal beds are thick and near the surface, such as in Wyoming, mining costs and coal prices tend to be lower than in locations where the beds are thinner and deeper, such as in Appalachia.
More than half of the coal mines operating in 2008 have since closed tags: map mining production/supply In 2018, coal production declined as exports and Appalachian region prices rose

Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step bystep mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
Some operations have very thin seams of coal that are not practical to recover using conventional methods. We can extract these seams with surface miners, lowering the strip ratio. Aggregate Operations. Surface miners reduce operating costs, increase recovery in areas of blasting restrictions and provide unique options for blending your material.
