Within the figure for coal, hard coal accounted for 12.9% and lignite for 11.8% of total primary energy consumption. Germany is dependent on energy imports to a large extent, except in the cases of lignite and renewable energy. About 90% of hard coal was imported, in comparison with 98% import dependence for oil and 90% for natural gas.
Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step by-step mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.
mining: room-and-pillar and longwall mining. In room-and-pillar mining, coal deposits are mined by cutting a network of 'rooms' into the coal seam and leaving behind 'pillars' of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam – although this coal can sometimes be recovered at a later stage.

It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals. Anthracite is the most metamorphosed type of coal, in which the carbon content is between 92% and 98%. The term is applied to those varieties of coal
Mining Anthracite. The extra pressure from this process yielded coal that was more pure, harder, and of higher carbon content than other types of coal.
