与西方发达国家相比,我国的选煤工业起步比较晚,二十世纪五十年代才开始逐步建立起自己的选煤工业。一直以来,我国的煤矿产量都很高,但是原煤入选率远远低于同期主要的产煤国家。二十世纪九十年代,我国选煤方法才逐渐改变以往的跳汰法,转而以重介选煤法为主。随着社会的发展,科学技术不断发展,引进国外先进的选煤技术,通过自身的努力研究,我国选煤技术呈现多样化形式。
Compared with the western developed countries, China’s coal preparation industry started relatively late, the 1950s began to gradually establish its own coal preparation industry. All along, China’s coal production is high, but the coal selection rate is far lower than the major coal-producing countries over the same period. In the 1990s, the method of coal preparation in our country gradually changed the previous jig method and turned to heavy medium coal preparation method. With the development of society, the continuous development of science and technology, the introduction of foreign advanced coal preparation technology, through their own efforts to study, China’s coal preparation technology presents a diversified form.
