The invention relates to the development of the clay deposits and can be used in the mining industry.

There is a method of field development, including technological scheme of movement of the scraper, producing the excavation and transportation of soil (Havaalan, Agonise. "Bulldozers, scrapers, graders. "The technology works". M.: Higher school).

The disadvantage of this method is that not ensured the development efficiency of the clay deposits.

The closest in technical essence and the achieved result is a scraper and dozer and scraper ways Stripping (Smokov. "Technology and complex mechanization of placer developments". Scraper method of Stripping operations. Dozer and scraper method of Stripping operations. Ed. 2nd, Rev. and ext. M., "Nedra, 1973. 786 S.), including excavation of rocks and systems Stripping operations.

However, this method does not provide drying of the soil.

Object of the invention is the drying of clay soils. This is achieved by the fact that in the way of the development of clay mineral deposits, including Deposit opening, layer-by-layer excavation of sand on the ground, warehousing and transportation for leaching, according to the invention, the polygon is divided into sections with a width equal to the length of the scraper is th zagadki, layer-by-layer in the recess produce alternating benches throughout the site area maximum thin shavings, and warehousing Sands produced in the stack adjacent to the width of the polygon area, as drying sand on the ground and in the technology stack repeat on adjacent along the length of the landfill sites and after dumping stacks of produce supply sand for leaching from the pile, after which the operation is repeated on the adjacent width of the sections in the opposite direction. The length of the plot is determined by the formula

where T is the required duration of the ground and pile, day;

Q - capacity scraper, m3/day;

hminthe minimum chip thickness, m;

In - the width of the plot m,

The width of the area should ensure that the condition

B=Vto/(BtoĚhmin),

where Vto- volume of a ladle scraper, m3;to- the width of the bucket scraper, m; hmin- the minimum thickness of the removable chip, m

The method of execution of works is illustrated by the diagram, where the I, II, III, IV - conditionally divided areas; 1 - scraper; 2, 3 - zagadki taking into account the rotation of the excavation; 4 - stack; B, L are the width and length of the plot. The polygon is divided into parts I, II, III, IV. The scraper 1 removes the soil a minimum thickness of the chip with section II and as you fill the bucket ships the ground in a pile of 4 related to the initial width of the polygon area I, where the soil is supplied to the washing. Layer-by-layer in the recess produce alternating benches throughout the site area maximum thin shavings, and warehousing Sands produced in the stack adjacent to the width of the polygon area I, as the drying of sand on the ground and in the technology stack repeat on adjacent along the length of the landfill sites and after dumping stacks of produce supply sand for leaching from the pile, after which the operation is repeated on the adjacent width of the sections in the opposite direction.

Drying is carried out under natural air as in the array and the stack. On the efficiency of drying is influenced by the following factors: the initial humidity and ambient temperature, the drying time and the degree of loosening the soil.

As a result of implementing the proposed works are created favorable conditions for drying clay rocks due to longer being outdoors in the array, and in the loosened condition in the stack. The technology is effective in a period of positive temperatures.

SUBSTANCE: invention refers to development of connate gravel deposits of solid minerals, particularly beach deposits of shelf. The method of development of connate water-flooded placers consists in preliminary concentration of useful component of sands in a lower part of the placer by means of excitation of elastic vibration and in successive stopped excavation. A tubular casing is introduced into the placer; the height of the casing exceeds the distance from the surface to the raft of the placer, excitation of elastic vibration in placer sands is performed by means of their transmission from surface via the tubular casing. Further a compressive force onto contacting surface, covering volume of empty material, is exerted from the side of interior surface of the casing. Then lower part of placer is hydraulically excavated by means of supply of washing water through nozzles arranged at walls of the tubular casing; pulp is withdrawn through soil draw-off apertures made at walls of the tubular casing between nozzles. Also after completion of excavation of lower part of the placer, pressure onto the surface, covering volume of empty material contacting with interior surface of the casing, is dropped to zero. When the cavity of the casing has been filled to a level corresponding to a ground level, the casing is pulled off.
