Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 180 ft (55 m), are usually surface mined.
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining
identified resources of black coal. The coals include a wide range of types and ranks, from high-volatile sub-bituminous coal to anthracite. Approximately half of the identified resources are amenable to open-cut extraction. This extensive endowment, coupled with a history of efficient and productive mining, a well-developed infrastructure and a highly skilled workforce, has resulted in the

Scope. The U.S. Geological Survey (USGS) Energy Resources Program, in cooperation with many agencies and scientists from the world’s coal producing countries, undertook a project, called the World Coal Quality Inventory (WoCQI), to obtain samples of coal from the world’s producing coal mines during a limited period of time (roughly 1995-2006).
Maps of the northern and central Appalachian Basin coal regions showing the distribution of known coal resources in the Lower Kittanning coal bed and the five assessed coal units: Pittsburgh coal bed, Upper Freeport coal bed, Fire Clay coal zone, Pond Creek coal zone, and Pocahontas No. 3 coal bed.
Coal is extracted from the earth through underground mining or surface mining. The choice of mining method is largely determined by the geology of the coal deposit and its distance to the surface. Underground mining currently accounts for a larger share of world coal production than surface mining.

Map Source: Statistica, Coal-mining employment in Virginia from 2009 to 2014, by mine type A major justification for that partisan claim was the decision by the Environmental Protection Agency (EPA) to regulate carbon dioxide as a pollutant, and to issue other regulations that could be a "train wreck" for coal-fired power plants.
After centuries of mineral exploration, the location, size and characteristics of most countries' coal resources are quite well known. What tends to vary much more than the assessed level of the resource i.e. the potentially accessible coal in the ground is the level classified as proved recoverable reserves.
