Abstract

The invention relates to an aluminum earth peel off, mining and cultivating method, which comprises: peeling off the band, and processing mining in open air; then processing band cultivation in the empty area or soil discharge area to make the peeling off and mining on one band. The invention can effectively shorten the time of cultivation as from 10 years to 3 years, to improve the environment.

Description

Bauxite stripping, the process of digging up mine, reclaim
Affiliated technical field
The present invention relates to a kind of mining, the process of reclaiming, particularly relate to a kind of process of peeling off, dig up mine, reclaim of suitable Opencast Bauxite Mine.
Background technology
Traditional bauxite technology of digging up mine-reclaim is to dig up mine after peeling off again, and has adopted behind the ore or reclaim after filling up in the refuse dump again.After promptly will showing soil and roof rock and peel off together, dig up mine again with peel-off device; Barren rock is transported to the goaf or store up the refuse dump, in layer increases the refuse dump, perhaps also expands the area of casting when increasing, and reaches the absolute altitude of final refuse dump at last, reclaims again.The characteristics of this traditional handicraft are continuous mining, casting, usually the capacity of goaf, refuse dump is bigger, but casting is more than 10 years, goaf, refuse dump equal open-assembly time is long, the cycle of reclaiming is long, the land seizure time is long, increases the mine cost, easily causes a large amount of soil erosions and the forfeiture of ploughing.
Summary of the invention
The invention provides a kind of Opencast Bauxite Mine process of peeling off, dig up mine, reclaim, purpose is to satisfy the needs that bauxite mining is produced and reclaimed, and shortens the time of reclaiming, and shortens the land seizure time, reduces land destruction, keeps the ecology of mining areas balance.
The inventive method has realized the peeling off of bauxite land reclamation technology and mine, mining, casting technology combines closely, unified planning and coordination are carried out, and has reached the organic unity of peeling off, dig up mine, reclaiming.
To achieve these goals the present invention be achieved in that bauxite stripping, the process of digging up mine, reclaim, first band is peeled off, and carries out surface mining after peeling off, in the goaf or the refuse dump carry out band and reclaim, the same band of peeling off, dig up mine is carried out.
It is exactly that a refuse dump that is about to form is divided into several bands that described band is reclaimed, and carries out the band casting in order, and each band of reclaiming once reaches final refuse dump absolute altitude, by the requirement of reclaiming, and the following discharging rock of the band of reclaiming, the discharging table is native above.
Described mining and reclaim and to carry out simultaneously.
Used equipment is large-scale scarifier and scraper in the described technology of peeling off, dig up mine, reclaim.
Advantage of the present invention and effect are as follows:
The present invention adopts band to peel off, dig up mine, reclaim, and making peels off, digs up mine, reclaims carries out in order, forms " peeling off-dig up mine-reclaim " integrated production new technique of reclaiming, and has overcome the defective that traditional handicraft is peeled off, dug up mine, reclaims and disconnect mutually; Being reclaimed in the refuse dump carries out in advance, can effectively shorten the time of reclaiming, the land used cycle of reclaiming was shortened to about 3 years by 10 years, can save investment or cost that ground, leased land are bought in the mine, according to the aluminous mine of one 500,000 tons of measuring and calculating, can reduce expenses more than 5,000,000 yuan.Make goaf, refuse dump become little Plain, the scabland ground that improves has promptly retained the water source, has effected a radical cure soil erosion again, can make the ecological environment in mining area be able to bigger change.
Concrete true mode
Bauxite stripping of the present invention, the process of digging up mine, reclaim, specific as follows: as to adopt band to peel off when peeling off, be about to bauxite and be divided into several bands and peel off; The band surface mining is carried out in position after peeling off; Goaf after mining or refuse dump are carried out band and are reclaimed, it is exactly that a refuse dump that is about to form is divided into several bands that band is reclaimed, plannedly carry out the band casting in order, each band of reclaiming once reaches final refuse dump absolute altitude, by the requirement of reclaiming, the reclaim following discharging rock of band, discharging table soil is dug up mine and is reclaimed and can carry out simultaneously above.Wherein peeling off, dig up mine, reclaim, used equipment is large-scale scarifier and scraper in the technology.Every operations such as soil, muck haulage, mining, pad soil, grading can be born and loosen the soil, be shoveled to scarifier and scraper.
Adopt scarifier-scraper band strip mining transformation new technology, adopt that band is peeled off, enhanced recovery, band are reclaimed, a series of measures of recycle circuit, form " peeling off-dig up mine-reclaim " integrated production new technique of reclaiming.By the arrangement of unified planning, work in coordination in time with on the space, accomplish that exploit on the limit, reclaim in the limit.

Claims (4)
