一、采煤(见表1—3)1980年12月末,生产煤矿的数目与1979年相同,仍为26个。1980年煤炭总产量为1802.7万吨,比1979年增产38.4万吨。各种煤炭产量比例为:焦煤为694.5万吨(占38.5％);动力煤为1107.5万吨(占61.4％);无烟煤为0.7万吨(占0.1％)。与1979年相比,焦煤相继减少5.7％;动力煤相继增加5.6％;无烟煤相继增加0.08％。按主要煤矿和其它煤矿划分的产量为:主要煤矿为1657.5万吨;其它煤矿为145.2万吨。1980年主要煤矿的产煤比例由1979年的92.5％下降到91.9％,即减少0.6％,但仍占产煤量的主要部分。按地区划分的产量为:北海道为1070.9万吨;本州为6.8万吨;九州为725万吨。这些地区的产量比例分别由1979年的61.2％、
I. COAL MINING (See Table 1-3) At the end of December 1980, the number of coal mines produced was the same as in 1979, still 26. In 1980, the total output of coal was 18.027 million tons, an increase of 384,000 tons over 1979. The proportions of various coal production are 6,945,000 tons (38.5%) of coking coal, 11,075,000 tons (61.4%) of steam coal and 7,000 tons (0.1%) of anthracite coal. Compared with 1979, coking coal has been reduced by 5.7%; steam coal have increased by 5.6%; anthracite have increased 0.08%. The output by major coal mines and other coal mines is 16,575,000 tons for major coal mines and 1,452,000 tons for other coal mines. In 1980, the proportion of coal production in major coal mines dropped from 92.5% in 1979 to 91.9%, or 0.6%, but it still accounted for a major part of the coal production. Production by region is: 10,709,000 tons in Hokkaido; 68,000 tons in Honshu; 7,250,000 tons in Kyushu. The proportion of output in these areas increased from 61.2% in 1979,
