西德煤矿在第二次世界大战时受到严重破坏。战后开始恢复生产,但技术落后,效率很低,成本很高。加上当时中东廉价石油大量输入,煤炭的竞争能力弱,严重束缚着煤炭的发展。为扭转这种局面,他们采取了一些措施和政策,主要对老矿进行技术改造,关闭一些生产困难的矿井,合并小矿为大矿,采用新工艺、新设备,提高机械化、自动化水平,实行科学管理,大搞综合利用,发展炼焦和发电等,很快使煤矿得到了发展。如萨尔煤炭公司5个矿,1977年每个矿平均日产原煤12788吨,共有23个工作面,每个工作面平均日产原煤2470吨。全公司共有职工21844人,其中采煤工人15030人。井下工效率为4.75吨/工(折原煤7.12吨/工)。公司5
West Germany coal mines were severely damaged during the Second World War. After the war began to resume production, but backward technology, low efficiency, high cost. Coupled with the large amount of cheap oil imported from the Middle East at that time, coal’s competitiveness was weak, seriously hampering the development of coal. To reverse this situation, they have taken some measures and policies to mainly carry out technological transformation of old mines, shut down some mines with difficulties in production, merge small mines with large mines, adopt new techniques and new equipment, and raise the level of mechanization and automation to implement Scientific management, vigorously promote the comprehensive utilization, development of coking and power generation, and soon the coal mine has been developed. For example, there are 5 mines in Sal Coal Company. In 1977, each mines averaged 12,788 tons of raw coal per day, with a total of 23 working faces with an average of 2,470 tons of raw coal per working face. The company has a total of 21,844 employees, of which 15030 coal workers. Downhole efficiency of 4.75 tons / workers (off crude 7.12 tons / worker). Company 5
