摘要
基于对嵩山煤矿原煤的粒度组成、密度组成、泥化特性等分析,根据煤炭市场形势与国家政策确定产品定位,并结合细粒级筛分与干法选煤技术发展状况,对该煤矿无烟煤加工提质方案进行探讨,同时预测了相应加工提质方案下的经济效益。
As requirement for coal market and national policy,product positioning is determined by analyzing raw coal features in Songshan coal mine,such as size composition,density composition,degradation features in water etc. In combination with status of development of fines screening and dry coal washing technologies,anthracite upgrading method is discussed,predicting its economic benefit.
