Abstract: A scientific and reasonable evaluation method of coal mining rights is conductive to realize optimal allocation of coal resources.With the rapid development of coal mining rights market,case-based evaluation method will become more and more important in coal mining rights evaluation in the future.Based on the theories and methods of case-based reasoning and modern statistics,this paper revealed the basic principle of case-based reasoning evaluation method of coal resource mining right,and defined the key concepts such as attribute index,attribute strength function,underlying asset,case assets,and case similarity.Then the criteria of case selection and the similarity model under the condition that attribute strength function was unknown were established.Finally a case-based reasoning evaluation model and evaluation procedures of coal resource mining right were set up.The established model was applied to a real case.The research results show that the price by using case-based reasoning evaluation method is very close to the final deal price.Furthermore,under the condition of a certain number of comparable transaction objects,this method needs less data and thus is more efficient and direct than other evaluation methods.
