Abstract
The invention provides a method for restoring the vegetation of pyrite abandoned mine, which comprises the steps of cleaning a field, adding lime, paving a matrix, spraying slurry, paving a second layer of matrix, planting plants, covering non-woven fabrics, maintaining and managing and the like.
Description
Technical field
The present invention relates to revegetation field more particularly to a kind of restoration methods of troilite abandoned mine vegetation.
Background technique
Troilite is that a kind of most wide sulfide mineral, also known as pyrite are distributed in the earth's crust, and main component is curing Asia
Iron (FeS2) sees the ore and rock of a variety of origin causes of formation often in the crystalline forms such as cube, pyritohedron or blocky aggregate
In.Color and bright metallic luster because of its pale yellow copper, are often mistakenly thought of as being gold, therefore also known as " fool's gold ".Simultaneously also
It is the essential mineral raw material for extracting sulphur, manufacturing sulfuric acid, it is a kind of anthrax, separately that special form color, which has ornamental value,
Outside, also there is medical value.
After pyrite mine is exploited, various types of metal sulfides are all contained on stratum, and soil is extremely barren severe,
Plant is difficult to grow, while these metal sulfides can produce oxidation and generate sulfuric acid after contacting with the air, more unfavorable
In plant growth.The soil formed in such circumstances is known as Minesite acid sulfate soils.The oxidation of sulfide is one natural
Process, this process are exposed in air in a large amount of high containing sulfur minerals and are accelerated.The oxidation of these containing sulfur minerals is produced
Raw acid can generate immediately and wide influence environment.Under certain conditions, sulfide mine is aoxidized with different rates.Sulphide ore
The oxidation rate of object will largely determine that the potentiality of production acid, key reaction formula are as follows:
2FeS2+2H2O+7O2→2FeSO4+2H2SO4
4FeSO4+2H2SO4+O2→2Fe2(SO4)3+H2O
Fe2(SO4)3+H2O→2Fe(OH)3+3H2SO4
Fe2(SO4)3+FeS2→3FeSO4+2S
2S+3O2+2H2O→2H2SO4
Traditional contaminated soil remediation is mainly based on the physico-chemical process such as soil moved in improve the original, Soil leaching, application stabilizer；This
There are also novel environment functional materials to be applied to contaminated soil remediation outside.But conventional physical chemical remediation technology for
Although it is short, quick to administer the serious contaminated soil time, it is usually associated with the risks such as high energy consumption, high cost, secondary pollution.
Chinese patent: the revegetation tectosome and its method for recovering vegetation of discarded metal mine mining site
(CN103548519A), a kind of revegetation tectosome of discarded metal mine mining site, stepped and every level-one are disclosed
Including being located at bottom and making with a thickness of the lkd layer of 5cm~8cm, the stalk layer on the upside of lkd layer, on the upside of stalk layer
Based on layer the soil moved in improve the original layer containing organic fertilizer and compound fertilizer, positioned at by hillside side rhone, positioned at from hillside side by stacking
The earth-retaining slope of soil moved in improve the original bag composition.The patent also discloses a kind of method for recovering vegetation of discarded metal mine mining site comprising: it will
The mine slight slope face of abandoned mine mining site is trimmed to step, and builds by laying gutter, slot, stacks soil moved in improve the original bag, paver grieshoch and stalk, visitor
Soil, acidproof, the impoverishment tolerant forest seedling of plantation or pioneer herbaceous plant and etc..Sour water is prevented by effectively dredging water flow in this patent
Diggings soil is polluted, and establishes " oxygen consumption layer " and inhibits the oxidation of sulfide effectively to reduce soil acidity and then repair pollution mine
Soil realizes the effect for repairing mine soil reduction revegetation greening protection environment.The technical disadvantages are to adjust soil pH using lime,
Dosage is not suitable for will lead to improvement in vain or soil is excessively alkaline, needs to carry out extensive soil moved in improve the original operation, at high cost.
Chinese patent: it is dirty to disclose a kind of mine for treatment method for recovering mine polluted land vegetation (CN103299799A)
The processing method of dye ground revegetation, method includes the following steps: removing the bulk float stone or prominent of mine pollution ground surface
Object out；Configuration resistance control isolated material；Resistance control isolated material is sprayed on impurely surface and forms resistance control separation layer；Using resistance control every
Absciss layer carries out closing isolation to impurely surface；It plants raw technology using fiber filament soil and slope protection and is rebuild on resistance control separation layer and plant life
Layer；And planting plants realize revegetation on planting generating layer.The processing method is by forming resistance control separation layer on mine surface
To play physics and chemistry closing buffer action, the acidity and heavy metal ion for preventing the possible reverse osmosis of mine deep layer are due to soil capillarity
Capillary action reverse osmosis is rebuild on the resistance control separation layer and plants generating layer to mine surface layer, provides good object for plant growth and development
The mine soil environment of Physicochemical property, to achieve the purpose that revegetation and conserve water and soil.The technical disadvantages are only
Resistance control isolation processing is carried out to original soil, original soil is still potential risk, and resistance control isolated material contains heavy metal ion, greatly
Amount use will cause heavy metal pollution hidden danger, and using artificial cellosilk, natural degradation time is long, increases new pollution to soil.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of restoration methods of troilite abandoned mine vegetation, make sulphur iron
Mine abandoned mine vegetation achieve the effect that fast quick-recovery, using agriculture and forestry organic waste material, such as crop material, dry branches and fallen leaves etc. is used as base
Matter carries out Organic Matter Enrichment to soil, while adding microorganism and accelerating revegetation.To realize the above-mentioned technical purpose, of the invention
The specific technical solution taken are as follows:
A kind of restoration methods of troilite abandoned mine vegetation, include the following steps:
Step S1: removing stone in troilite abandoned mine, and the ground of the troilite abandoned mine is made to keep smooth；
Step S2: quick lime layer is laid on the level land in the troilite abandoned mine；Mine is discarded in the troilite
On hillside in mountain, injection quick lime slurries form quick lime layer, and the quick lime layer is with a thickness of 20cm or more；
Step S3: being laid with one layer of agriculture and forestry organic waste material on the quick lime layer, forms the first agriculture and forestry organic waste material layer；
Step S4: spraying mud on the first agriculture and forestry organic waste material layer, forms mud layer；
Step S5: one layer of agriculture and forestry organic waste material is laid on the mud layer and forms the second agriculture and forestry organic waste material layer；
