Coal mining - Coal mining - Choosing a mining method: 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 depends on many .

Whether excavating or hauling limestone or other natural resources, we have the skills to ensure your operation is productive and cost-efficient. As part of the more than 100-year-old North American Coal Corporation, North American Mining operates and maintains 30 draglines, ranging from 7 to 124 CYD machines, and an electric rope shovel.
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.
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations. All costs listed are in 2012 US$.
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.

Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step by-step 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.

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.
High-grade, clean coal; Efficient, low-cost production; We have a diverse portfolio of four mining operations in Utah and Colorado that produce an aggregate of 13 million tons of high-BTU, low-sulfur bituminous coal. Our mines include some of the most productive and longest, continuously-operating mines in the United States.
An increase in productivity will decrease coal mine capital and operating costs, and each ton of increased productivity per man-day can be expected to save the nation approximately $7 billion (1975 dollars) in the price paid for coal over the next 10 years.
Surface Coal Mining Methods in Australia 5 2. Open cut mining methods strip mining Large-scale open cut coal mining operations commenced in Australia in mid 1960s and since then there has been significan t developments in this method of mining. The mines are now operating at significantly higher annual tonnages, growing deeper, more complex and
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 U.S. because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.
The final result of the cost-sheet is now merely a question of cross-footing the various operating accounts, and balancing with the line called Total Cost of Mining. This gives, of course, the amounts in the total debits column, and summing these up gives the total cost of operating the mine.
