Abstract: Currently,coal is still the main resources of energy in our country,the level of sustainability supply is affected by various factors.By reviewing the literature,we have built an index system with eight dimensions,including the exploration of coal,control- planning objectives completion rate, "three rate" and so on.Acquiring research data,based on the entropy value method to process and access to weights,and then weighted by index evaluation method to comprehensive evaluate the sustainability of supply level of coal resources.The results show that coal exploration and imports play major roles,the sustainability of supply level showing the downward trend of twists and turns.By analyzing the supply and demand of coal,coal economic development,the author will put forward thinking and exploration from the coal exploration,imports, "three rate" and demand further.
