Simultaneously, be accompanied by the discharging of a large amount of solid waste spoils in the coal production, its traditional processing mode is to be carried to accumulation on ground surface by the down-hole, forms the distinctive topographical features in colliery " building " hillock.According to incompletely statistics, about 4,500,000,000 t of gangue of whole nation accumulative total stacking over the years at present, larger hillock has more than 1600, about 1.5 ten thousand hectares of land occupation, and also accumulating amount also increases with the speed of 1.5~2.0 hundred million t every year.The discharging spoil brings very big threat and harm to existent environment of people and condition, mainly shows: appropriation of land; Contaminated environment; Harm humans safety.
Therefore, how under the prerequisite that guarantees surface buildings safety, solve bar coal mining post partially recycled and spoil (comprise from down-hole rock and coal rock drift road, chamber tunnel go out spoil and ground washing spoil) handling problem become the great technical barrier of coal mining.
Summary of the invention
The purpose of this invention is to provide band exploitation protection coal column spoil replacement exploitation method under a kind of building.
For achieving the above object, band exploitation protection coal column spoil replacement exploitation method is under the building of the present invention:
(1) protection class that requires according to the buried depth of strip coal pillar, width, overlying strata structure and surface buildings is in each strip coal pillar central authorities 3~5 waste filling lane of centralized arrangement;
(2) to 3~5 waste filling lanes earlier driving mine filling waste rock from inside to outside in the tunnel of extraction coal then.
The lanewidth in 3~5 waste filling lanes of described each strip coal pillar central authorities centralized arrangement is 3.5~5.0m, and the lane is high identical with coal seam thickness, and coal pillar width is 4.0~6.0m between the filling lane.
Described driving to 3~5 waste filling lanes tunnels Centromedian one earlier, behind the coal in the extraction lane, waste filling is carried out in this tunnel, tunneled the waste filling lane of next strip coal pillar central authorities simultaneously, by that analogy, until the exploitation of finishing last strip coal pillar and filling; And then, tunnel the waste filling lane of each strip coal pillar the same side successively from first strip coal pillar, and carrying out the displacement of spoil and coal, the driving in 3~5 waste filling lanes in finishing each strip coal pillar is mined and waste filling.
The invention has the beneficial effects as follows: the control above ground structure is in the surface deformable scope that allows, in band coal mining post, arrange the waste filling lane, with waste filling replacement exploitation coal, band coal resources under surface plant, the building are implemented secondary recovery, can realize that bar coal mining post spoil replacement exploitation coal resources are not less than 20%, territory, bar exploiting field resource amounts to the rate of recovery and is not less than 65%; Can guarantee the safe handling of surface buildings; Can realize the whole digging gangues of mine, part ground spoil in the filling treatment of down-hole, the pollution of effectively avoiding face of land spoil to pile up; Realize that disposal cost is lower than floor treatment under the waste shaft, and (comprehensive benefit in 4.0 * 5.0m) is not less than 7000.0 yuan/m in the filling lane.Through the mining area type approval test, obtained good effect, not only eliminated the ground hillock, reduced and occupy the farmland, reduce atmosphere and environment pollution, elimination hillock are caved in or ignite the accident potential that jeopardizes the mankind; And can solve or reduce on the basis of the surface settlement and the problem of subsiding with the direct underground filling of spoil as the underground structure supporter, the realization recovery section is built down coal resources.
