Mar 08 2013 Hundreds of miners at Britain's deepest coal mine which was devastated by an underground fire were given the sack by text it emerged today.In Australia nearly 80 of coal is produced from open cut mines in contrast with the rest of the world where open cut mining only accounts for 40 of coal production Open cut mining is cheaper than underground mining and enables up to 90 recovery of the in situ resource.
The major source of fuel throughout the world is coal Coal is a black or brown rock that when burned releases energy in the form of heat One of coal’s main uses is the production of electricity.Map of kettlebottoms in an eastern Kentucky coal mine and photograph of large kettelbottom from the mine Where one kettlebottom is detected are likely Known Kentucky occurrences Kettlebottoms have been reported above many of the mined coals in eastern Kentucky Published reports give examples above the Blue Gem (Greb 1991) Pond Creek.
