粉煤灰改良基质对矿山尾石覆盖区复垦的研究

Research of Improved Matrix of Fly Ash Reclaim to Abandoned Mine

为研究粉煤灰改良基质对矿山碎石层的复垦效果,采用工业燃烧废物粉煤灰,与醋糟、土壤等配比形成优良基质来铺撒矿山尾砂覆盖区,使基质渗漏填充砂化的矿山尾石层,然后在基质表面正常播种,待出苗后追踪测定植株的覆盖率、生长变化规律和生长状态。结果表明:植物可以在其上生长,生长状况良好,此方法可以作为废弃矿区生态再恢复的研究手段之一。

To research on the effect of the improved matrix of fly ash on reclaiming the gravel layer of mine,the way of spreading and filling the gravel layer with matrix in proportion of industrially burning waste fly ash,vinegar and soil. The result of tracking the coverage and growth rule indicated that plant could grow on the reclaimed gravel layer and the growth condition was good. So this way could be used as one of research approa-ches of studying reclaim of abandoned mine.
