Ecological restoration method for passivating heavy metal activity of mine slope
The invention discloses a passivation heavy metal activity mine side slope ecological restoration method which sequentially comprises the following steps that S1, a side slope is trimmed, geological investigation is conducted on the side slope, and an unstable area is cut off; s2, an anchor rod is arranged, the anchor rod is installed after the slope surface is drilled, and cement paste is injected to stabilize the anchor rod; s3, a modifier is applied, and vinasse, traditional Chinese medicine residues and mushroom residues are applied to the side slope; s4, hanging a hot-dip galvanized wire mesh, anchoring the hot-dip galvanized wire mesh into the anchor rod, and covering the modifier with the hot-dip galvanized wire mesh; s5, spraying a soil dressing layer, and spraying the muddy mixed base material to the slope surface; s6, grass seeds are sprayed and sown, and a base material containing the grass seeds is sprayed to the slope surface; and S7, maintenance management: immediately covering non-woven fabric after spray-seeding is completed, and performing watering, topdressing and disease and pest control maintenance management at regular time. The activity of the heavy metal is passivated through the modifier, the heavy metal is fixed in the original place through the plants, pollution diffusion of the heavy metal is reduced, a good root growth environment for the spray-seeding plants is created, and the ecological environment of the mine slope is repaired.
本申请公开了一种钝化重金属活性的矿山边坡生态修复方法，依次包括如下步骤：S1修整边坡，对边坡进行地质勘察，削掉不稳定的区域；S2锚杆打设，坡面钻孔后，安装锚杆，并注入水泥浆稳固锚杆；S3施撒改良剂，将酒糟、中药渣、蘑菇渣施撒在边坡上；S4挂设热镀锌铁丝网，将热镀锌勾花铁丝网锚入锚杆内，盖在改良剂之上；S5喷射客土层，将泥浆状混合基材喷射至坡面；S6喷播草种，将包含草种的基材喷射至坡面；S7养护管理，喷播完成后马上覆盖无纺布，并定时进行浇水、追肥、病虫害防治养护管理。本发明通过改良剂钝化重金属活性，利用植物将重金属固定在原处，减少了重金属的污染扩散，创造了喷播植物较好的根系生长环境，修复了矿山边坡的生态环境。
