铁法矿区煤的基本特征及其微量元素

系统地研究了东北地区最大的动力煤供应基地铁法矿区长焰煤的资源、性质及其有益、有害微量元素的分布。发现铁法煤中的硫、磷、砷、氯等有害元素及铅、铬、汞等重金属元素的含量均较低,是辽宁省内主要燃煤电厂的重要优质煤源。 According to studied the resource characteristic and the distributing of its useful and harmful microelements of longflame coal in Tiefa mining area,which is the biggest provider of power coal in northeast of china,it was found that the useless elements such as sulfur,phosphor,arsenic and chlorine,and heavy metals of lead,chrome and mercury are few in this coal,and it is also the important coal origin with high quality of some primary electric power plants within Liaoning province
