Deutsche Steinkohle is Germany's Old King Coal. The operating subsidiary of Germany's RAG Aktiengesellschaft, Deutsche Steinkohle (DSK) is the country's largest coal mining company. Its coal is used primarily for steel production and power generation. DSK operates seven mines in NorthRhine-Westphalia, one in the Saarland, and a coking plant in NorthRhine-Westphalia. RAG and Deutsche Steinkohle are owned by the state-run RAG Foundation, which was set up to oversee the dissolution of the German coal industry. The German government decided in 2007 that economic and environmental conditions make it infeasible to continue coal production in the country going forward, and so the industry will wind down by 2018.
