Surface/open cast mining and deep underground mining are considered two basic methods for coal extraction globally. The rising trend of coal mining activities has resulted in the accumulation of mining and processing wastes with low carbon levels over the past few decades [6]. Fig. 1 presents different life cycle stages of coal with details of wastes generated at each stage.
The history of coal mining dates back to over 400. million years ago. Coal mining started in Midlothian, Virginia (near. Richmond) in 1748. Coal machines were available in the 1880s. The oldest deepmine facility is the Tower. Colliery, located in the UK, in 1805. Surface mining was started in 1912. 3.

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. In surface mining, giant machines remove the topsoil and layers of rock to expose large beds of coal. Once the mining is finished,
6. COAL GASIFICATION UNDERGROUND COAL GASIFICATION (UCG) PROCESS • Under the process of UCG, gasification of coal happens insitu by controlled burning. • About 350 m3 gas can be produced per tonne of coal. • Bye products of significant commercial value will be hydrocarbons, phenols, anhydrous NH3and clean water • UCG overcomes hazards of underground and open cast mining operations.
