Abstract: The open-pit coal resource mining has caused great environmental pressure to the semi-arid region of Xinjiang where the ecological environment is fragile. Therefore, it is particularly important to evaluate the ecological disturbance and calculate the ecological value loss caused by the resource mining under the specific environment. According to the characteristics of semi-arid ecologically fragile area and the ecosystem service function under special environment, the ecological cost of mine is divided into direct economic value loss, exogenous ecological value loss, environmental pollution control cost, ecological cost of energy consumption, and reclamation cost, and the ecological cost model of open-pit coal mine in a semi-arid ecologically fragile area is established. The research results are applied to a specific open-pit coal mine in the semi-arid ecologically fragile area of Xinjiang, and the ecological cost of the mine is 2.328 billion yuan, accounting for 94.90% of the net present value of the mine. It can be seen that the ecological disturbance and ecological cost caused by resource exploitation in the semi-arid ecologically fragile area are severe, and if the mine takes the ecological cost into account in the mine financial statistics, it may experience significant reduction in profit.

Key words: ecological cost; the ecologically fragile area of semi-arid; open-pit coal mine; ecological reclamation; green mines
