The utility model belongs to the field of ecological restoration of mines, in particular to a vegetation restoration technology for slope of mine dump. The vegetation restoration structure of mine acid dump slope includes water diversion hole, water diversion pipe, isolation layer and matrix layer. The water diversion pipe is buried under three-dimensional network as a whole, and the water diversion pipe is \7\ type, and the shorter end is inserted into the water diversion hole. The isolation layer consists of three-dimensional net, clay and straw curtain. The structure of the isolation layer is that the three-dimensional net is located at the bottom, then filled with clay, and finally covered with straw curtain. Both the straw curtain and the three-dimensional net are anchored by U-rivets. The substrate layer is the plant growth area, located above the isolation layer. The utility model realizes a virtuous cycle of ecological restoration by guiding the discharge of acid leachate, isolating and covering, preventing further acidification, and further controlling the diffusion of environmental pollutants through the restoration of vegetation.

一种矿山酸性排土场边坡植被恢复结构
本技术属于矿山生态修复领域,尤其涉及一种矿山排土场边坡的植被恢复技术。
技术介绍
矿山开采对我国的经济快速发展具有不可替代的作用,同时也给生态环境造成了破坏。在矿山开采过程中,特别是露天开采场不可避免的会遗弃大量非矿石类废渣,他们集中排放的场所会形成排土场,排土场不仅会侵占大量土地,它也是一种巨型人工堆积的结构松散型山体,若不及时处理,不仅会造成水土流失、甚至泥石流,同时,其废渣中存在的金属硫化物,在遇水和空气的环境下,还会浸出大量含重金属的酸性废水,给周边环境造成极大环境污染。对堆土场进行植被恢复不仅能够降低水体流失风险,它还是控制排土场重金属酸性废水污染的有效措施。而针对酸性排土场的植被恢复,土壤中高浓度的重金属以及极性酸性却是限制植物生长的重要限制因子,也是植被恢复的难点所在。
