Abstract

The invention relates to mining and can be used in the hydraulic laying of rocks in the dumps and tailings. The purpose of the invention is to reduce the cost of storing the rocks by reducing the cost of forming dam embankments. Along the contour of the inlet area of the water dump, piles-coolers 1 of the freezing system are installed, introducing their lower ends into the soil of the base 10 of the dam. Piles-coolers are poured by imported primer or from reserve, and the resulting dam 2 body is frozen. , building up the dam to the contour 3. The soil of the dam, which has been poured again, is frozen and alluvium of the second river begins. In such a sequence, the dam is frozen to the size at the time of completion of the reclamation of rocks in the hydraulic mine dump in the area. 2 Il.

The invention relates to mining and can be used in the hydraulic laying of rocks in the dumps and tailings, in particular - for the formation of embankments.

The purpose of the invention is to reduce the cost of storing the rocks by reducing the cost of forming dam embankments.

FIG. 1 depicts a hydraulic dump (map of alluvium) in plan, covered with soil

FIG. 1 shows a hydraulic dump (map of alluvium) in plan, covered with a ground-ice dam; in fig. 2 - section A - A in FIG. I.

In the drawings, piles-coolers 1 are marked, sprinkled with imported (or from a reserve) soil 2, circuit 3 of the body of the dam, filled with it; the body of the dam 4 at the time of completion of alluviation of rocks in the dump; sand ditch 5 for discharging clarified water from the settling pond 6; layer (rus) of washed-up rocks 7; an overflow pipe 8 with a thermal insulator 9, laid under the dam body from the well pit; 10 base oTBa.ia. 11 - drainage ditch.

The principle of laying rocks using this method is as follows. Along the contour of the inlet area (one or several maps) of the hydraulic dump, pile coolers 1 are installed, inserting their lower ends into the ground of the base 10 on the tub, for example, 20-30 cm, so that they stand steadily until they are filled with soil. At the same time, the chandry company is built (according to the traditional principle), the toe 5 with the overflow pipe 8 protected from freezing by thermal insulation 9. Then the cooling piles 1 (and the overflow pipe 8) are dusted with imported soil (or outdated) and frozen in the formed the body of the dam (the so-called primary embankment) to a height of | Ruta 2.

Then, the usual process of feeding the pulp to the dam-contoured zone begins, alluvium of the 7th Russa rock is washed up to its calculated thickness (taking into account the height of the soil 2 of the filled dam). The clarified water from the sump pond 6 of the hydraulic dump is discharged from the alluvium zone through the spun well and the overflow pipe 8 into the drainage ditch 11. After all the first rushes are washed in, the pulp is temporarily stopped (or switched to another alluvium card), the pile coolers 1 are again sprinkle with already washed soil, raise (build up) the dam constructed in this way, for example, to circuit 3. Then pour ground soil into the ground and freeze the 2nd Rus. In such a sequence, the dam 4 is frozen to the size at the moment of completion of the alluvium rocks in this dump (alluvium map).
