Harder coals are found deeper underground than lignite and are mined differently from the way lignite is mined.
Bovey Tracey Lignite
Lignite was worked around Bovey Tracey in Devon. It formed in the Lower Miocene epoch, of the Neogene Period, between 23 and Mya, and was worked here intermittently until 1945. The beds of lignite which have been mined sporadically since the early 16th century, were formed in the bed of an ancient lake, which was mined by opencast methods.
lignite
Most lignites are geologically young, generally having formed during the Cenozoic (Cenozoic Era) and Mesozoic (Mesozoic Era) eras (approximately 2 to 250 million years ago).Many lignite beds lie close to the surface and are of great thickness, sometimes greater than 30 m (about 100 feet); they are easily worked, and the cost of production is low.
