The utility model belongs to ecological restoration of mine field, sets gradually fine and close barrier layer, crude fibre organic horizon from below to up.Fine and close barrier layer is formed by ore in sand form soil, cement, binder, quick lime by volume proportion, crude fibre organic horizon is made of plant fiber clast and binder, the binder is vinyl acetate based polyalcohol, the plant fiber clast is one or more mixtures of wood sawdust, stalk clast or withered branch clast, and the plant fiber clast partial size is 1-5mm.The separation layer of Mine Tailings library acid soil revegetation is located at the lower part of the planting area of Tailings Dam acid soil, is bottom tailing soil below separation layer.The utility model works simultaneously from physics and chemical means, obstructs the migration and conversion of the toxicant in tailing acid soil, provides good growing environment for revegetation.
Description
Technical field
The utility model belongs to ecological restoration of mine field more particularly to a kind of revegetation skill in Mine Tailings library
Art.
Background technique
Mining has irreplaceable role to the rapid economic development in China, while also causing to ecological environment
It destroys.In metal mine recovery process, especially concentrate mineral processing circuit can generate a large amount of tailing ore in sand form, these tails
Mine can not only occupy a large amount of soils, and tailing itself is also important pollutant source, if administering not in time, can bring to periphery huge
Overall situation pollution, tailings are the important means of Revegetation of Eco-environment.
Since tailing is to contain a large amount of weight in the solid particle that ore is processed by a series of technique of preparing and is generated
Metallic element, such as copper, lead, zinc, cadmium, content are often much more than the prescribed limits of normal soil；Contain in tailing toward contact
There are a large amount of metal sulfides, metal sulfide under conditions of meeting air and water is very easy to that acidic materials are precipitated, while acid
Under the conditions of can also further promote the precipitation of heavy metal, this is all the revegetation working line of tailing into restrictive condition.
In tailing during reclaiming, no matter using revegetation is carried out after traditional covering with new soil or original soil improvement, every
The setting of absciss layer is all very necessary, it is possible to prevente effectively from soil harmful substance further precipitation, and to planting soil
The osmosis pollution of earth saves economic cost.
Utility model content
The purpose of the utility model is to provide a kind of separation layers of Mine Tailings library acid soil revegetation, simply
It conveniently realizes and Tailings Dam acid soil is effectively isolated, create good plant growth environment for its revegetation.
To achieve the goals above, the utility model provide a kind of Mine Tailings library acid soil revegetation every
Absciss layer, feature are: including fine and close barrier layer, the crude fibre organic horizon set gradually from below to up；The fine and close resistance
Compartment thickness is 3-5cm, is formed by ore in sand form soil, cement, binder, quick lime by volume proportion；The crude fibre organic horizon
With a thickness of 1-2cm, it is made of canebreak；The separation layer of Mine Tailings library acid soil revegetation is located at the metal
The planting area lower part of mill tailings library acid soil.
Optionally, the volume ratio of the ore in sand form soil, cement, binder, quick lime are as follows: 6:1.5:0.5:2.
Optionally, the volume ratio of the ore in sand form soil, cement, binder, quick lime are as follows: 6.8:1:0.2:2.
Preferably, the canebreak partial size is 1-5mm, and canebreak is carried out by adding a certain proportion of binder
Solidify skinning.
The beneficial effects of the utility model are: Mine Tailings library acid soil revegetation provided by the utility model
Separation layer, on the one hand can chemically form isolation, cement and quick lime are basic matterial, can not only be neutralized in soil
Acidic materials, moreover it is possible to chemical passivation be carried out to heavy metal, reduce heavy metal activity；On the other hand, can physically be formed every
From being added with binder in fine and close barrier layer and crude fibre organic horizon, cement be also added in fine and close barrier layer, makes to obstruct
Layer can form rock-steady structure and space, the migration of toxicant effectively be obstructed, in addition, the organic substance in crude fibre organic horizon
The organic composition that barrier layer can also be supplemented after degradation, provides excellent growing conditions for plant.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram of the utility model；
In figure: 1, fine and close barrier layer；2, crude fibre organic horizon；3, planting area；4, bottom tailing soil；
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is further described.
