某露天煤矿生态足迹和生态包袱的分析

    Analysis of ecological footprint and ecological rucksack of a open-pit coal mine

    • 摘要: 煤炭是我国的主要能源,在一次能源消费构成中煤始终占70%以上,煤炭开采一方面给我们提供主要的能源,另一方面又给生态带来巨大压力。采用生态足迹与生态包袱相结合的方法对某煤矿露天矿的生态压力进行分析,结果显示,露天矿的生态足迹是化石能源地和林地,主要生态足迹是化石能源地,其恢复生态承载的最佳途径以植树造林为主。注重采矿环节,改进技术以降低剥离和掘进量,例如通过优化设计,尽可能增大露天矿最终帮坡角,降低剥采比。降低电耗和提高水的循环利用率,采用清洁能源和生物能源等措施以降低露天矿的生态压力。

       

      Abstract: Coal isChina’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.
