Yes, there is non-recoverable coal. When coal resources are inaccessible or too deep to economically mine, or when they are in areas that are off-limits for mining due to environmental or other restrictions, this coal is considered non-recoverable.
At the end of 2008, Australia had 69,310 million metric tons of recoverable coal reserves, 8.9% of the world's total.
Coal is found in Baluchistan, Upper Punjab and in Thar Desert. Thar desert holds the largest coal reserves in Pakistan and this coal is also known as Thar Coal.
There is some discussion of this in Jeff Goodell's "Big Coal." 25% of the world's "recoverable" coal deposits are in the United States (270 billion tons.) Russia is next with 176 billion tons, much of which is in areas difficult to mine. This information is on page xvi in the introduction of his book. You will probably find move specific information about your question if you investigate his book's sources as listed in the Notes section of his book.
Coal deposits are commonly referred to as coal seams or coal beds. These are layers of coal that are found buried beneath the Earth's surface.
Baluchistan province of Pakistan is full of mineral resources. Large deposits of coal, chromites, gypsum, marbles, copper, iron ore, and gold have been found in Baluchistan.
The Country that has the known (proven) coal deposits in Africa is South Africa which is said to have reserves of 50 billion tonnes of coal.
"Thar" coal field in pakistan is the biggest one
Coal deposits are layers of sedimentary rock containing coal, formed from the accumulation of buried plant material over millions of years. These deposits are mined for coal, which is a fossil fuel used for electricity generation and heating. Coal deposits can vary in thickness, quality, and location around the world.
Pakistan is a developing country and we cannot use renewable power resources due to lack of finance and technical assistanceWe donot have alternative sources of energy due to the requirement of the people and various industries we do mining of coal and use of various industries especially in thermal power plantsWe have fewer deposits of oil and low quality coal
Wyoming has the most coal deposits in the southwest region of the United States. It is the top coal-producing state in the country due to its extensive coal reserves and mining operations.
Layers of sediments compressed the layers of vegetation to form the coal deposits.
