古交西山矿区煤矸石山生态修复模式研究与探讨

Research and Exploration on the Mode of Gangue Hill Ecological Restoration in Gujiao Xishan Coal Mine

在生态学理论指导下,古交西山矿区依据当地的气候、土壤及煤矸石的特点,合理地选用乔木、灌木,牧草多种植物对矿山进行了生态修复,修复后的矿山,植物的多样性大大增加,土壤表面温度下降,空气湿度增加,有效地抑制了矸石山的自燃,同时矿山表面有毒元素含量也大大降低,矸石山生态环境得到恢复,古交西山矿区煤矸石山生态修复模式,对北方矸石山的植物修复具有一定借鉴和指导意义。

Under the guidance of the ecological theory, and according to the local climate as well as the characteristics of the soil and gangue, Gujiao Xishan Coal Mine carried out its ecological restoration by selecting trees, shrubs and grass varieties of plants. The diversity of plants has been greatly increased af- ter restoration, soil surface temperature has also decreased, and the air becomes more moisturized, which in turn curb the spontaneous combustion of the gangue hill, and meanwhile the toxic element of the sur- face is therefore diminished greatly. As a result, the whole ecological environment has been restored, and the mode of gangue hill ecological restoration in Gujiao Xishan Coal Mine has served as an instruction and reference for the restoration of the gangue hill in the north China.
