摘要
根据鸡西地区的煤质结构，以1／3焦煤替代部分气煤炼焦，既提高了焦炭的机械强度，又保证了城市供气需要，为鸡西地区焦化厂选择炼焦煤种提供了依据。
Accomplishing coke production by replacing part of gas coal with 1/3 of coke, as is allowed by the coal quality structure in Jixi area, serves not only to improve the mechanical strength of coke, but also to ensure coal gas supply to cities. The Practice offers a basis for the coking plants located in Jixi area to select the kind of coal for coking
