How many years of coal is left?
Based on U.S. coal production in 2019, of about 0.706 billion short tons, the recoverable coal reserves would last about 357 years, and recoverable reserves at producing mines would last about 20 years. The actual number of years that those reserves will last depends on changes in production and reserves estimates.
How deep is coal usually found?
Coal that occurs at depths of 55 to 90 m (180 to 300 ft) are usually deep mined, but in some cases surface mining techniques can be used. For example, some western U.S. coal that occur at depths in excess of 60 m (200 ft) are mined by the open pit methods, due to thickness of the seam 20–25 metres (60–90 feet).
Is Coal still being formed?
The process of coal formation is still taking place today, says Bailey. “The precursor to coal is called peat, and that is just uncompressed plant matter.” Peat accumulates in wet swampy environments known as mires, and that process is taking place today in areas such as Indonesia and even the Antiplano in the Andes.

How is coal mined today?
Open-cut mining is possible because coal seams are close to the surface. Such mining is cheaper than underground mining and enables up to 90% recovery of the resource. … The surface rock (called overburden) covering the coal is then blasted with explosives and removed by excavators.
