Coal Preparation in Germany and the Netherlands

PRIOR to the war just ended, Germany was the greatest coal producer in continental Europe. In 1943 the production of coal, bituminous and higher in rank, together with brown coal calculated to the equivalent amount of bituminous coal, is estimated to have been about 240 million metric tons, according to the War Department. Before the war production in Germany exceeded consumption. No other country in continental Europe except Poland had a large surplus. However, England's surplus was the largest in Europe as a whole. Before World War II the Ruhr Basin normally supplied about 70 pct of the total production of high-rank coal, the Saar and Aachen about 6 pct each, Upper Silesia about 14 pct, and Silesia and Saxony the remainder. Nearly one third of the brown coal was produced in the Rhineland, a little less than one half in central Germany west of the Elbe River, and about one fourth east of the Elbe. Bituminous coal and brown coal together constituted by far the most important energy resources of the old German Reich. Bituminous coal furnished nearly 70 pct of the total energy requirement, brown coal supplied about 25 pct, and water power, wood, petroleum and alcohol together aggregated only 7 pct. Because it was the most important single mineral resource of Germany, an excess of coal enabled the Reich to import nearly all the other mineral products that she lacked, such as iron ore from Lorraine. The area adjacent to the coal fields was supplied with gas from an interconnected grid. Similar electric grids are based on brown coal with the power stations at the mines. Coal tar provided the foundation for the development of the extensive German chemical industries as exemplified by the I. G. Farbenindustrie. For almost a century, German scientists have been adequately supported both by the State and by industry in studying improved methods of utilizing coal. In Germany the mineral rights were reserved by the State and ordered extraction of coal was enforced. Each lease comprised a relatively extensive area, which accounts for the generally large size of the mines and mining companies. In 1938 there were 160 mines in the Ruhr, with a total output of 125 million tons but go pct of the production was controlled by 20 companies. By far the largest single coal-mining company in Germany was the Gelsenkirchener Bergwerke A. G., which produced nearly 27 million tons in the Ruhr in 1937. Second was Saargruben A. G., a State-owned company operating in the Saar, which produced more than 13 million tons. Third was Bergwerksgesellschaft Hibernia A. G., with 10 million tons, also in the Ruhr. Briquettes are made from both bituminous coal and brown coal, but in 1938
