Exports of coal in 1946 amounted to 27,366 tons, as compared with 21,989 tons in 1945. In 1946, 2,265,170 tons were produced from underground mines,, compared with 2,380,896 tons in 1945, and from opencast mines 528,700 tons were produced in 1946, as against 452,680 in 1945. The output per miner employed underground was 593 tons, a decrease of 13 tons as compared with 1945. The production per man on the pay-roll of underground mines—i.e., both underground and surface workers —was 441 tons, a decrease of 12 tons on the previous year. Production per man employed in opencast mines was 1,244 tons, a decrease of 119 tons as compared with 1945. The over-all production per man employed in the industry —i.e., combined underground and opencast mines—amounted to 503 tons, a decrease of 4 tons as compared with 1944.
