英文摘要：

This paper discussed four kinds of coefficient for measure the similarity between different objects and proposed a method of determining optimal industrial application of coal by absolute distance.Taking coal quality data from 4 mines of Datong coal area as the example,and based on the national standard of the coal industrial application,this paper quantitatively evaluated the optimal industrial application of coal of each coal mine by the absolute distance model.
