(54) METHOD OF EDUCATION DUMPS OF EMPTY BREEDS

The cost and timing of construction are sufficient; Yes. ,,.: The goal is achieved by the Chgöm, which in the well-known method of forming waste dumps during mining

and geological minerals with a tailing facility with the subsequent laying of dry overburden YORB and recultivation. Alluvium on the CLOSES with NSH layers is carried out with overlapping of it ka sd 5d :); The previous layer is the next. moreover, after laying at least two layers, dry overburden is laid. In addition, the crests of the layers form with a slope of 1-2% from. Central longitudinal. Axis tailings. izsebryot yi prn luyuyu devil, they are depicted: in fig. 1 longitudinal section of the combined dump; in fig. 2 is a plan of FIG. one; on, .fig. 3 -; section A-A of FIG. one.

The method is as follows.

 in a way. :,:, .... .., ...., .. i ,, „.,.:.„ „.,“., 1.1., -, -

previously at the bottom of the Gbalka ravine, hollows) 1 in its lower reaches; A dam (dam) 2, for example, up to 5 to 10 m high, is designed to create a settling pond 3. A discharge pipe 4 is laid along the dam to return clarified water from the pond to the process-. The process of the processing plant.

Mount the floating pumping station / tank 5, which is connected to the pipeline 4 by the floating pipeline 6.

Around the perimeter of the blade is performed. drainage ditch 7 with a slope in the direction of the dam (Fig., 2 and 3).

The top of the ravine (girder) is placed at the point 8 / .potterechnyYDtUzhYvv-9 with outlets,: directed towards the dam and from HaioiohoiM from the central section of the tailings deposit of 1-2% (fig. 3)

in the direction of the ditch 7.- - -

After alluvium is 40-80 cm, the layer of pul- des is lifted. The lawn rises to this height with the help of the pipelayer. This operation is repeated until the crest 10 has a predetermined design elevation. - -When performing this operation, natural tail segregation occurs and the first inclined layer is formed at an angle of repose. At the same time, the larger fractions of xyosts are distributed in the upper part of the layer, and the small particles are carried away, with k |

Then, the slurry line 9 is transferred to point 11 and, the next inclined layer is washed up to the left side, similar to the second one.

At the same time, the large Lraktsy at the crests of the yoyola of the first common inclination

layer overlap smaller scrub. The tails of the preceding layer are formed in the form of v in t of bp; from standard skeleton ;; pb 1y (material) I5 of material, KpyriWdct

which gradually decreases to the lower marks of the tailings.

When each subsequent layer is washed up with a slurry transfer step 9 (i 30–300 m), saddles 12 are formed between adjacent layers, replicating a slope of 1-2% slurry line 9. Most of the water flows down the sloping surface of the layer toward the dam into pond 3, and part of the water on the saddles 12 may drain into the ditch 7.

After completing the two or three layers, we start to form horizontal layers 13 of dry overburden, which are placed on the formed ridge ends of the inclined layers and the saddles 12.

As the dry heap gradually develops and when it reaches the design elevation mark (area of points 8, 10, 11), the developed section 14 reclaims and transfers it to agricultural production.

It is possible and Other, the implementation of the method with the repetition of all the listed operations, but with the replacement of the operations of periodical vertical lifts of the slurry line 9, the operation of installing this slurry line on the racks (supports), the height of the KOTopbix. t in that it eliminates the need for separating cold tailings, separating the sections and washing all the jumpers between them, simplifies the technology of laying tailings, shortens the time of the start of dumping of dry dumps, the timing of recules to offer and transfer plots for agricultural production.

Invention Formula   li A method for the formation of waste dumps during mining and mineral processing with a storage facility filled with injecting sloping layers in the direction from its headwaters, followed by laying dry overburden and recultivation, in order to simplify the technology and reduce the time reclamation, alluvium sloping. the layers are carried out with the overlapping of each previous layer followed by, and after laying, at least two sloevs, dry bedrock rocks are laid. 2. The method according to p. 1, IT l and h ayusch. And 1 with the fact that. the crests of the layers form with a slope of 1-2% from the central longitudinal axis of the tailing stock.
