Abstract: Underground coal mining plays a significant role in coal resource exploitation,with the establishment and development of green mine as the basic requirement in the future.How to scientifically evaluate the green level of underground coal mining is the key to green mine construction.During this process,reasonable evaluation index system and weight distribution are crucial.In order to make the weight distribution more scientific and accord with reality,interval-valued intuitionistic fuzzy entropy is introduced and applied to the precision of the interval evaluation of expert system.Meanwhile,the paper adopts contingency theory to confirm the final weight as well as highlight the restrictive impact of weak links,leading underground coal mining on the road of green mine development in a balanced way.All these contribute to the level of green mine.At last,the effectiveness is verified by way of numerical instances.Constructive advices are put forward for future green coal establishment.
