Đọc thêmLignite is Abundant and Accessible. Western North Dakota has over an 800-year supply of lignite that is currently accessible and economically feasible to recover. 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.
Đọc thêmThe softer and moister lignite (also called brown or soft coal) has a lower calorific value than hard coal and can only be mined in opencast operations. When burned, it is more CO2 intensive than hard coal. To date, opencast lignite mining has altered 179,490 hectares of countryside in Germany.
Đọc thêmLignite, generally yellow to dark brown or rarely black coal that formed from peat at shallow depths and temperatures lower than 100 °C (212 °F).
