河北省现有统配矿务局(矿)七个,生产矿34个,设计能力二千九百五十二万吨,采掘机械化程度:一九七七年分别为37.76%和29.36%;七八年分别为43.31%和35.06%;七九年分别为42.57%和38.34%;八○年上半年分别为44.75%和36.69%。两年来由于采掘机械化程度逐年提高,进一步挖掘了矿井的生产潜力,使原煤生产也有显著上升,一九七八年生产原煤4365.9万吨,一九七九年生产原煤4406.9万吨,均比正常年度产量提高15%左右。实践证明:发展煤炭工业的根本出路良于机械化。

There are seven existing unified coal mines (mines) in Hebei Province, producing 34 mines with a designed capacity of 29.52 million tons. The degree of mining mechanization is 37.76% and 29.36% respectively in 1977; 43.31% and 35.06% respectively in the past eight years, 42.57% and 38.34% in 1979 and 44.75% and 36.69% respectively in the first half of 1980. In the past two years, as mining mechanization progressed year by year, the productive potential of mines was further tapped and the production of raw coal also increased significantly. In 1978, the production of 43,659,000 tons of raw coal and 440,690,000 tons of raw coal were produced in 1979, Production increased about 15%. Practice shows that: the basic outlet for developing the coal industry is better than mechanization.
