Study on coal resources capacity evaluation based on DEA

By analyzing the evaluation methods for the coal resources capacity,an evaluation system for the coal resources carrying capacity was constructed in this paper.A C~2R model was established by the Data Envelopment Analysis(DEA) method to analyze and evaluate the coal resources carrying capacity.By this model,a case study on the coal resources in Heilongjiang Province was carried out,and objective conclusions of the coal resources capacity efficiency were acquired.It can provide references for the further study on the optimization of coal resources carrying capacity and the allocation,utilization and management of coal resources in Heilongjiang. Finally,countermeasures of enhancing the coal resources carrying capacity for Heilongjiang Province were suggested.
