近几年来,由于库兹巴斯高灰难选煤的产量增加、水力采煤的发展和采掘机械化程度的提高,造成原煤质量恶化,煤炭含矸率、末煤量和水分增加。该煤田的原煤灰分从1970年的15.1%增长到1982年的17.1%,而运往选煤厂的入选原煤灰分从18.1%增到19.7%。为了提高商品煤的质量,库兹巴斯煤田正通过建设新的选煤厂和用新技术、新工艺对现有选煤厂进行技术改造来大力发展选煤工业。西伯利亚中央选煤厂采用了煤泥直接
In recent years, due to the increased production of high-ash refractory coal in Kuzbass, the development of hydraulic coal mining and the enhancement of mining mechanization have led to the deterioration of raw coal quality, the coal refuse rate, the end coal quantity and the moisture increase. The coal ash content of the coalfield increased from 15.1% in 1970 to 17.1% in 1982, while the ash content of the selected raw coal shipped to the coal preparation plant increased from 18.1% to 19.7%. In order to improve the quality of commercial coal, Kuzbass coalfield is developing its coal preparation industry through the construction of a new coal preparation plant and the technical transformation of the existing coal preparation plant with new technologies and processes. Siberian Central Coal Preparation Plant used slime directly
