The embody rule of the linkage that the utility model provides:
2-2 coal seam, great Liu tower ore deposit and 5-2 coal seam spacing 155m, 3 coal mine underground reservoirs are built in 2-2 coal seam respectively, 5-2 coal seam is current working seam, application coal mine underground reservoir technology, this ore deposit has realized mine water zero-emission, for the mine water ensureing 5-2 coal seam industrial water and is produced generation recharges three, 2-2 coal seam groundwater reservoir and carries out purified treatment, need the connecting pipe between construction two coal seam, if employing traditional approach, the pipe laying cycle is long, build and maintenance cost compared with high and potential safety hazard is large.
Application the utility model method of attachment of providing, between 2-2 coal seam and 5-2 coal seam, a design and construction boring 11, arranges four drainage pipelines simultaneously.First, by geological prospecting and supply and discharge water demand etc., determine to adopt the boring of diameter 1.4m to arrange 3 drainage pipelines simultaneously, comprise boring 11 and the ducts facility of Φ 1.4m.Boring 11 dark in about 155m, drainage pipe diameter is 423mm, two water supply line diameters are respectively 423mm and 219mm; Groundwater reservoir weep hole A position construction in upper coal seam, build the vertical drilling 11 of 1.4m diameter, and arrange above-mentioned 3 drainage pipelines, the clear water of the groundwater reservoir in 2-2 coal seam is connected with 5-2 coal seam gravity line or supply channel respectively through methane drainage and utilization project water supply line, for 5-2 coal production and application; Meanwhile, the mine water in panel, 5-2 coal seam three recharges pipeline or drainage pipe by the mine water in vertical drilling, injects 2-2 coal No. 3 groundwater reservoirs, recharges the mine water yield day and be about 2880m3, achieves the closed cycle of Underground well water and utilizes.
According to traditional approach, arrange along tunnel, then need tubing distance about 15km, be made up of three pipelines, comprise drainage pipe, water supply line and backup line, the pipeline according to diameter 159mm is laid, construction cost about 1,700,000 yuan; And in the same boring of the utility model, arrange that many pipeline fees only need about 800,000 yuan, above-mentioned expense not yet considers regular maintenance and operational and administrative expenses, can find out that the utility model technology application benefit is obvious.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, other modification some can also be made, also should be considered as protection domain of the present utility model.
