摘要：
The principle of green mining is conservation resources, protection environment, people oriented and safety production. According own characteristics of coal industry, this paper built the input and output indicators of green mining, chose eight different coal enterprises in China as decision making units. The date envelopment analysis (DEA) was applied to evaluate and optimize the operating efficiency of coal enterprises from technical efficiency, pure technology efficiency and scale efficiency. At the same time, with an inefficiency enterprise as example, projection analysis was used to give some suggestions to optimization.
