Description
Technical field
The present invention relates to mining junkyards to plant raw reparation field, and specifically a kind of the Northeast's magnesite mining junkyard is temporarily planted life and repaired
Compound method.
Background technique
Giobertite is one of Chinese Dominant Mineral Resources, large-scale, superior in quality, based on sparry magnesite.Northeast ground
Area possesses 29.31 hundred million tons of resource reserve, accounts for 62.13% that the national same period possesses resource reserve, accounts for world's magnesite resource reserves
21.2%, it ranks first in the country, has world's advantage.In magnesite recovery process, a large amount of low-grade magnesite She Yan are deposited in row's rock
, soil, pollution environment are not only covered, but also will cause geological disaster.Mining junkyard is by rubble and slagheap of different sizes
Product forms, severe water and soil erosion, and vegetation is difficult to nature growth, and environment remediation difficulty is very big, and as technique of preparing and mineral are deep
The progress of processing, these low-grade magnesites can be arranged in future by open and access again, therefore using permanent mine environment reparation
It applies, will increase the difficulty of subsequent open and access again.
Summary of the invention
A kind of the Northeast's magnesite mining junkyard of being designed to provide of invention temporarily plants and gives birth to restorative procedure, above-mentioned to solve
The problem of background technique.
The technical scheme of the present invention is realized as follows:
A kind of the Northeast's magnesite mining junkyard temporarily plants raw restorative procedure, including clear slope, cuts that slope is smooth, digs pit, earthing, spreads
It broadcasts, be laid with plant-growth carpet, cuttage bamboo willow, organic matter of sowing grass seeds by duster, a kind of the Northeast's magnesite mining junkyard temporarily plants raw reparation
Method, including construction procedure in detail below:
(1) clear slope: slope surface and platform are greater than 30cm stone and are crushed to 10cm hereinafter, screening, 1cm ~ 10cm rubble are put into gabion
In, as bottom of slope slope protection barricade, it is less than 1cm particulate slag as planting soil raw material for standby；
(2) it is smooth to cut slope: mining junkyard is accomplished into multiple steps, using mechanical and artificial smooth slope surface, makes slope surface without obvious protrusion；
(3) it digs pit: digging cave using mechanical, be 1m × 1m according to spacing, cave diameter is 0.3m, and depth is the specification of 0.3m ~ 0.4m,
Slope surface and step are scraped out into fish-scale pit shape；
(4) earthing: by hole, slope surface, platform, mulching plant is native simultaneously, and entire slope surface is shakeout using machinery after earthing；
(5) broadcast sowing: the native table after step (4) earthing carries out sowing grass-seed and shrub seed, and it is big that the kind of grass-seed is chosen to be awns grain husk
Wheat straw, summer cypress, lyme grass, the kind of shrub seed are chosen to be beans tea Cassia, and the cover of 1cm ~ 5cm soil is covered after sowing；
(6) it is laid with plant-growth carpet: being laid with plant-growth carpet after step (5) is broadcasted sowing, using reinforcement stalk plant-growth carpet, be from top to bottom followed successively by
PP reinforced bar net, polypropylene sizing net, rice, corn stalk fiber layer, matrix fiber weight is 260g/ ㎡ ~ 300g/ ㎡；
(7) cuttage bamboo willow: the cuttage bamboo willow in the fish-scale pit that step (3) has been dug, bamboo willow select fast-growing bamboo willow, bamboo withy bifurcation intercept
Height is 25cm ~ 30cm, and depth is 15 cm ~ 20cm in cuttage to planting soil；
(8) it sows grass seeds by duster organic matter: after step (7) cuttage bamboo willow, sowing grass seeds by duster organic matter on plant-growth carpet surface, wet curing 1 time weekly,
Maintenance 10~15 times.
Into one step of ground, the step (2) cuts smooth the controlled slope surface angle in slope within 45 °, slope surface fine grained mine
Slag or gravel mulch.
Into one step of ground, the thickness of earth covering of hole is 0.35m ~ 0.45m in step (4) earthing, and slope surface and platform cover
Soil thickness is 0.1m ~ 0.15m.
Into one step of ground, planting soil used in step (4) earthing by soil, particulate slag and organic solid waste compost according to
4:4:2 is mixed.
Into one step of ground, Four Plants seed awns Hordeum jubatum, summer cypress, lyme grass, beans tea Cassia that the step (5) is broadcasted sowing
Mass parts ratio be 10:2:2:1, by Four Plants seed after mixing per acre sow 3.5kg ~ 4.5kg.
Into one step of ground, it is 2.35m that the step (6), which is laid with plant-growth carpet width, overlaps 8cm ~ 10cm between plant-growth carpet, use is U-shaped
Nail is fixed, and plant-growth carpet is laid with since platform, close to the ditching of slope surface position, buried portion plant-growth carpet, so that plant-growth carpet is from top
It is fixed.
Into one step of ground, step (7) the fast-growing bamboo willow growth period is fast, after 2 years can topping be used as biological particles material.
Into one step of ground, step (8) organic matter is made of compost, stalk clast, water-retaining agent, adhesive, compost and straw
Stalk clast ratio is 1:1 ~ 1.2, and water-retaining agent incorporation is 0.1% ~ 0.2%, and adhesive bleed and amount are 0.05% ~ 0.1%.
When mining junkyard is redeveloped and utilized, bamboo willow is cut down from root, takes bamboo willow root, is transplanted to next recovery project
In, bamboo withy bifurcation can section be truncated into 25cm ~ 30cm segment, the cuttage material as next engineering.Meanwhile dialling and removing U-shaped nail, from top
Plant-growth carpet is rolled according to overlap joint sequence in end, and plant-growth carpet can be directly used in next place's mining junkyard recovery project, in bottom of slope gabion
Ore can directly develop and use.After cleaning, low-grade magnesite can open and access again.
The invention has the benefit that
1, the present invention is mainly suitable for mining junkyard temporary reinstatement, and material is easy to obtain, at low cost, and grass-seed and shrub are selected and be suitable for
In the kind to the growth of the Northeast's magnesite mining area, magnesite basic soil condition is adapted to；Select biomass energy raw material bamboo
Willow carries out cuttage, and the plant variety speed of growth is fast, adapts to the Northeast's environment, can be gathered in by topping mode, in Pai Yan
Before the development and utilization of field, energy source raw material can be continually provided, the economic benefit that bamboo willow generates makes up mine and repairs investment；It selects and adds
Muscle plant-growth carpet, weather-proof, anti-rain drop erosion, plant-growth carpet is fixed using cuttage bamboo willow and U-shaped nail, stronger, avoids plant-growth carpet
It is dispelled by strong wind, while bamboo willow cuttage, reduces U-shaped nail dosage, save the cost；
2, cave of the present invention plants mode and reduces planting soil dosage, and planting soil is mixed by soil, particulate slag and organic solid waste compost,
Soil moved in improve the original amount is reduced, and subsequent development utilizes convenient disassembly, plant-growth carpet can rot to decompose in 2 ~ 3 years, and the later period only needs felling bamboo willow, digs
Bamboo willow root is taken, is transplanted in next recovery project, the ore in bottom of slope gabion can be developed and used directly, low-grade after cleaning
Magnesite open and access, this circulation pattern can greatly reduce mining junkyard rehabilitation cost again.
