摘  要: Coal is China's major energy, the composition of it has more than 70% at primary energy consumption, on the one hand, coal mining provides us with the main energy, on the other hand, it gives a tremendous pressure on ecology in the mining process. Analysis the ecological pressure of a open-pit coal mine with using the method of ecological footprint and ecological burden, the result shows that the ecological footprint of open-pit is the fossil energy land and woodland. Main ecological footprint is the fossil fuel energy land, The best way to restore the ecological carrying mainly to afforest. Meanwhile, pay attention to the mining areas and improve technology to reduce the amount of stripping and tunneling (for example, by optimizing design to increase the final pit slope angle and decline stripping ratio), lower power consumption and increase water recycling, the use of cleaner energy and biological energy and other measures can reduce the ecological pressure of open-pit coal mine.
