摘要
针对开滦唐山区域炼焦煤资源下降,需要依靠配洗、配销为主要增量途径的情况,为充分发挥开滦炼焦煤优势,满足焦化行业的质量需求,通过对选煤厂生产和煤质分析,确定了保持煤种分类指标在国家标准之内,维持简单混煤,肥煤、焦煤热反应强度在50%以上的配洗、配销原则。
Based on the situation of reduction Group, it is needed to rely on mixed washing of coking coal resouce in Tangshan coal field of Kailuan and saling to increase the coking coal output. In order to make full use of the advantages of coking coal in Kailun Group, satisfy the requirement of quality of co-king industry, analyzed the production of coal preparation plants and coal quality, determined the princi-ples of mixed washing and saling, that is guarantee the coal classificiation index wthin the limit of nation- al standards, maintaining the simple mixing, and the thermal strength of fat coal and coking coal more than 50%.
