Abstract
The invention discloses a method for recultivating collapsed soil in coal mining, which belongs to the technical field of the recultivation of collapsed soil. The method for recultivating the collapsed soil in coal mining comprises the following steps of: carrying out water pumping on accumulated water in the collapsed soil, adopting surface water pumping for a swampland and carrying out a next step directly if no accumulated water exists; digging trapeziform pits in the collapsed soil after water pumping and digging to an underground part at 4 to 5 meters deeply; constructing a methane tank in each pit in which earth is taken out, carrying out back filling by the original soil and using the residual earth for covering a collapsed area; covering a surface layer by using the soil after air outlets and feed ports, which are required by the methane tanks, are remained at the upper faces of the methane tanks, wherein the covering soil reaches 0.8 to 1.2 meter(s); and developing a planting industry and a breeding industry to the soil after treatment. The method for recultivating the collapsed soil in coal mining has the beneficial effects that methane tanks are constructed by utilizing the earth of the collapsed soil of an ore area, and the upper faces of the methane tanks are covered with the soil for planting trees, flowers and the like to develop the planting industry and the breeding industry after the methane tanks are constructed. In this way, a bottomland is lifted, the recultivation of collapsed soil is also realized, the full utilization of soil is achieved, and the utilization rate of the soil is greatly enhanced.
Description
Technical field
The present invention relates to a kind of method of reclaiming with mining landslide, belong to the land reclamation technical field of subsiding.
Background technology
Land reclamation is to soil occupied because of digging, building materials industry development and other industrial and mining waste accumulations etc. or that destroy; Make the production capacity that loses obtain utilizing again again through the regulation transformation; Be to solve the contradiction that industrial and mining enterprises such as digging, building materials and agriculture, forestry, animal husbandry, fisheries are striven ground, prevent the pollution of the environment, the effective way of ecology recovering balance.
Cause surface collapse like the mining area underground mining, when the face of land height after subsiding is lower than before the topsoil water level, or fall ponding in the subsidence area when being difficult to drain, original good farmland will become marsh or lake.Land resources for more and more precious is huge waste.The subside traditional approach of ground land reclamation of tradition mining area mainly adopts the gangue refill mode, subside earlier toward the mining area the backfill spoil and then on spoil earthing.There is following shortcoming in this method: quantities is big, cost is high; The backfill spoil is not enough, can't realize all backfill earthing of subsidence area.
Therefore, change the subside traditional approach of ground land reclamation of mining area, suit measures to local conditions, be built into cultivable good farmland, promote the improvement and the protection of mining collapse area ecotope from the angle of the circular agriculture chaor that will subside.
Summary of the invention
To the problem that above-mentioned prior art exists, the method that the present invention provides a kind of landslide ground of mining to reclaim, utilize the mining area subside the soil build a methane generating pit, accomplish making full use of of soil, improved land utilization rate greatly.
To achieve these goals, the technical scheme that the present invention adopts is: a kind of method of reclaiming comprises the steps: with mining landslide
(1) draw water: the ponding in the landslide ground draws water, and marshland takes the surface to draw water, if no ponding directly carries out next step;
(2) excavate: scrape out trapezoidal hole in the landslide ground after drawing water, deep-cut to underground 4-5 meters;
(3) build a methane generating pit: in taking out each hole of the earthwork, build a biogas generating pit, former earthen backfill surplus earth is topped as the subsidence area;
(4) earthing, shaping: gas outlet, charging aperture top layer afterwards that on biogas generating pit, reserving biogas generating pit needs cover with soil, and earthing reaches 0.8-1.2 meters;
(5) soil utilization: to the soil after step (4) processing, development plant husbandry and aquaculture.
An identical hole is dug at 3-5 meters at the every interval of step (2).
Build a biogas generating pit, promptly centralized biogas generating pit in each hole.
But the good farmland is cultivated in surplus earth backfill reparation.
The invention has the beneficial effects as follows: utilize the soil, ground that subsides, mining area to build a methane generating pit, build up behind the biogas generating pit on biogas generating pit the earthing kind and set, grow flower etc. and develop plant husbandry and aquaculture; So both low-lying land was raised, making full use of of soil accomplished in reclaiming of the ground of having realized again subsiding, and improved land utilization rate greatly; Reasonable Protection land resources, social economy and environmental benefit are high; For the mining area subside ground land reclamation a kind of technology of being convenient to promote is provided.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
To combine accompanying drawing that the present invention is described further below.
As shown in Figure 1, a kind of method of reclaiming with mining landslide, specific embodiment comprises the steps:
(1) draw water: according to situation on the spot, then at first draw water if having ponding in the landslide ground, marshland takes the surface to draw water, and after ponding is drained, deep-cuts to underground 4-5 meters.
(2) excavate: with scraping out trapezoidal hole in the landslide ground of excavator after drawing water, an identical hole is dug at 4 meters at every interval, and the centre has soil can connect ground vapour like this, helps the growth of top farming.
(3) build a methane generating pit: in each hole of above-mentioned steps, build a biogas generating pit, promptly centralized biogas generating pit, former earthen backfill surplus earth is topped as the subsidence area; , the former earthen backfill surplus earth of biogas generating pit of building 300 cubic metres is topped as the subsidence area, and every pond can go out a cubic metre of earth 515m3, but removes also subside 950 square metres of marshlands of 0.5 meter of overlying soil of the backfill earthwork.
(4) earthing, shaping: gas outlet, charging aperture top layer afterwards that on biogas generating pit, reserving biogas generating pit needs cover with soil, and earthing reaches 1 meter.
(5) soil utilization: to the soil after step (4) processing, development plant husbandry and aquaculture.
Build the 50000m3 biogas generating pit and take 260 mu of marshlands, but surplus earth backfill reparation can be cultivated the good farmland for 240 mu.
Fowl and animal excrement, sewage etc. are introduced in the pre-treatment pond and grow grass, foreign material cleaning back gets into acidification pool; In acidification pool, get into regulating reservoir after the descum; Arrive the anaerobic fermentation pond again, the natural pond slag is processed into granular fertilizer, and natural pond liquid sprays fertilizer as liquid; Biogas gets into gas storage holder after the desulfurization deodorizing, supply with user or generating through pipe network.Both can realize the resident living central gas supply, improve living environment, and can reduce the life spending again, practice thrift conventional energy resource, improve utilization efficiency of energy.
