Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom.. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining projects.When the top of the excavation is the ground surface, it is referred to as a shaft; when the top ...

Coal in Indiana was discovered along the banks of the Wabash River in 1736. Organized development of Indiana's coal resources began in the 1830s and by 1918, production exceeded 30 million short tons. Coal production declined following World War I, but underground (deep) mining remained the primary mining method in Indiana until the 1940s.

Coal Mining. Types of Coal Mines. There are four main types of coal mines: shaft mine, slope mine, drift mine, and surface (open-cast) mine. The mine at Coalwood was a shaft mine; the coal was brought up in an elevator from 600 to 800 feet underground. The University of Kentucky has an interesting diagram showing each of the four types of mining.

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.

SGS uses the results from ultimate analysis tests to determine the elemental composition of the coal including moisture, ash, carbon, hydrogen, nitrogen, sulfur, and oxygen (by difference). We determine each element through chemical analysis and express it as a percentage of the total mass of the original coal or coke sample.
