Soilless continuous greening method for mine waste rock/storage yard
The invention discloses a non-soil replacement greening method for a mine barren rock/tailing storage yard, which comprises the following steps: crushing a part of mine barren rock to prepare barren rock powder, and mixing a part of barren rock powder with lignocellulose, a fertilizer, a water-retaining agent, an adhesive and grass seeds to prepare a greening substrate; the slope surface and the plane of the storage yard are trimmed, and a framework and concrete are adopted on the slope surface for slope protection and stabilization; the waste stone powder is laid in a framework and on the plane of the slope surface, fertilizer releasing microorganisms are inoculated on the waste stone powder, and nutrient elements difficult to use are converted into available components through the activation effect of the microorganisms; then, the regreening substrate is laid on the plane and the slope inoculated with the fertilizer releasing microorganisms, the non-woven fabric is used for preserving soil moisture, when the cultivated regreening plants are maintained until the seedlings completely emerge and the seedlings grow to 10 cm, the non-woven fabric is removed, the nutrient immobilization microorganisms are inoculated, and then the plants grow naturally. Therefore, the mine waste rocks can be effectively utilized as raw materials for regreening, and the soil replacement-free remediation technology is achieved.
本发明公开了一种矿山废石/尾矿堆场的无客土复绿方法，其复绿步骤为：取部分矿山废石粉碎制成废石粉，取部分废石粉与木质纤维素、肥料、保水剂、粘合剂、草种混合制成复绿基质；对堆场的坡面及平面进行修整，在坡面采用骨架和混凝土进行边坡防护稳固；将废石粉铺设于坡面的骨架内部以及平面上，再在废石粉上接种释肥微生物，利用微生物的活化作用将难利用养分元素转化为可利用组分；然后将复绿基质铺设于接种有释肥微生物的平面及坡面上，用无纺布进行保墒，待养成的复绿植物养护至完全出苗且苗长至10cm时，撤除无纺布，接种养分固持微生物，之后让植物自然生长。可见，本发明可有效利用矿山废石作为复绿的原材料，实现无客土修复技术。
