Benefits of Lignite | Lignite Energy Council

Lignite is more accessible than other types of coal because lignite veins are located relatively near the surface, eliminating the need for underground excavation in tunnels. Surface mining also eliminates the risk of methane or carbon monoxide buildup, a primary safety concern in underground mining. Lignite mining is not totally without risk.
