摘　　要：为了促进煤炭产业的可持续发展,从经济学角度分析了外部环境成本和回采率提高成本,建立了最佳回采率分析模型,分析了最佳回采率的经济含义,指出企业在综合考虑社会、环境和资源的可持续发展的情况下,按照最佳回采率开采可以取得最大的收益。我国目前的回采率远远低于最佳回采率,存在较大的提升空间,值得煤炭管理部门和企业在提高回采率方面下一番功夫。In order to promote the sustainable development of coal industry, from the viewpoint of economics, the external environmental cost and recovery ratio cost for coal industry are analyzed, and an optimum recovery ratio analysis model is set up. The economic meaning of recovery ratio is analyzed, and points out that the maximal income will be acquired if the coal mining is carried out by the optimum recovery ratio in the case of the sustainable development of society, environment and resources are taken into consideration synthetically. At present, the recovery ratio of coal is far lower than the optimum recovery ratio and there is a huge space to advance in our country, so the efforts are needed to improve the recovery ratio of coal for the administrant departments of coal industry and coal mining enterprises.
