Description
Technical field
The invention belongs to environmental protection and agricultural synthesis to utilize field, is related to Abandoned Land of Mine restorative procedure, more particularly to a kind of
By method of the Abandoned Land of Mine reparation into nursery land used and a kind of conditioned soil being used for by Abandoned Land of Mine reparation into nursery land used.
Background technology
In mining mineral resource, especially metallic mineral resources recovery process, because total resources is limited, as mineral products provide
The raising of source producing level, ore can mining grade accordingly reduce, barren rock, mine tailing discharge rate are also sharply increasing.At present I
The barren rock in state mine, comprehensive utilization of tailing rate are relatively low, and substantial amounts of barren rock, mine tailing are stacked, and not only occupy a large amount of soils, and useless
Stone, resource of tailings are not also utilized rationally, while cause environmental pollution and potential safety hazard to surrounding area.
Further, since table soil is eliminated or scooped away in mining process, what is left after mining is typically cubsoil or slag, is added
The weight of large-scale winning equipment, often make soil hard, hardened.Mining area surface collapse forms the subsidence basin of large area simultaneously,
Being improved because phreatic table is relative easily causes soil to grow salination, is not used to nursery planting land used.Therefore, to chats,
Mine tailing is comprehensively utilized, while the technology for taking into account nursery planting is urgently developed.
The content of the invention
In order to solve the problems, such as to be deposited in background technology, by substantial amounts of research and experiment, applicants have invented one kind by ore deposit
The method that nursery land used is repaired on mountain discardedly.
This method mainly includes the following steps that：
(1) carry out classification processing respectively to mine tailing and barren rock, and sort out by size fractionated screening；
(2) mine tailing of certain grade obtained by sizing screening is well mixed as antiseepage application of anti-leakage layers with sludge, water-loss reducer；
(3) it is the mine tailing of certain grade obtained by sizing screening and the barren rock of certain grade is well mixed as ventilated
Layer；
(4) mine tailing of certain grade obtained by sizing screening is mixed with to the hypothallus for nursery planting with auxiliary material；
(5) using the barren rock of certain grade obtained by sizing screening as vaporization prevention layer；
(6) antiseepage application of anti-leakage layers, ventilated layer, hypothallus and vaporization prevention layer are laid on Abandoned Land of Mine successively, it is described anti-
The thickness for oozing application of anti-leakage layers is 20~30cm, and the thickness of the ventilated layer is 15~20cm, and the thickness of the hypothallus is 30
~50cm, the thickness of the vaporization prevention layer is 10~20cm.Technical scheme system of the present invention is comprehensive by proportioning test many times
Close conclusion to form, each thickness degree is suitable in scheme, ensure that economy and technique effect and perfect unity.If impervious barrier thickness mistake
Thickness, then technical costs is excessive, and excessively thin anti-seepage effect is bad；The too thin then air permeable effect of air-permeable layer is poor；If hypothallus is too thin, it is unfavorable for
Plant growth, too thick then cost is too high, and water permeability is also poor；Vaporization prevention layer is too thick ventilative bad, and too thin vaporization prevention effect is poor.
Preferably, also include the barren rock and mine tailing that do not meet grade condition carrying out break process respectively in step (1)
Step, until filtering out qualified barren rock and mine tailing.
Preferably, the grade of selected mine tailing is -0.2mm in step (2), and the volume ratio of -0.2mm grades mine tailing and sludge is
3.4~4:1~1.5, water-loss reducer is polyacrylic acid potassium and starch graft acrylic acid potassium, polyacrylic acid potassium addition is 100~
110g/m3, starch graft acrylic acid potassium addition is 1000~1200g/m3, utilize the proportioning, it is possible to achieve water conservation best effective
Fruit.The setting of this layer, mine useless ground too fast loss of moisture caused by the lax problem of native stone, nursery after enhancing improvement can be prevented
The water retention property of land used.Selection -0.2mm grade mine tailings, beneficial to compacting.
Preferably, the grade of selected mine tailing is+0.2mm in step (3), grade -10mm ,+the 0.2mm grade of selected barren rock
Mine tailing and -10mm grade barren rocks volume ratio are 3.5~4:1~1.5.+ 0.2mm grades mine tailing and -10mm grade barren rock phase interworkings
Close, that is, solve big granularity not water conservation the defects of, solve the air-locked problem of small grain size again.The setting of this layer, is advantageous to seedling
The diffusion of plant root air is planted in garden, effectively prevent excessive water accumulation from causing rotten, be unfavorable for the defects of plant growth.Root
Situations such as according to floristics to be cultivated, location precipitation, weather, the proportioning of mine tailing and barren rock can be chosen as desired, happiness
The suitable barren rock large percentage in area more than non-irrigated plant, precipitation, watercress, the suitable mine tailing large percentage in the area of little precipitation.
Preferably, the grade of barren rock is 10mm~20mm in the step (5).Land used is discarded in ore deposit due to being hidden without vegetation
Lid, is also blocked, easy excessive vaporization without periphery tree shade, is caused soil moisture evaporation too fast, is caused water-retaining property to be looked into, crop survives
Rate is low, it is necessary to frequently keep the skin wet, the problems such as increasing manpower and materials cost, the setting of vaporization prevention layer, advantageously accounts for mine and gives up
Ground is used for the water conservation problem in nursery.
Preferably, the grade of selected mine tailing is+0.2mm in step (4), and the auxiliary material includes organic fertilizer, haydite, water conservation
Agent, wherein, the organic fertilizer mainly includes kitchen garbage, municipal sludge, animal wastes, agriculture and forestry organic waste material, the haydite grain
Level is -5mm, and the water-loss reducer is polyacrylic acid potassium.
