The unit refers to the mining industry and is intended to be disjointed production of minerals from the seabed of the continental shelf.

A device for underwater development disjointed rocks, including dredge with a pressure pipe, the ends of which are located on the bottom of the reservoir, and hadagreed for feeding refrigerant in the pressure line, is further provided with an accumulating container enclosed in a spherical dome and provided with a heating element across the width of the container where the defrosting gruntilda bodies and land subsidence in the collection container while filling device raise for transporting the rope to the surface of the pond. Discharge pipe is located radially around the perimeter of the spherical dome (RU 74663 U1, IPC E21C 50/00 from 06.02.2008 published 10.07.2008).

The drawbacks are the cost of time and material resources for the trucking operations associated with the uplift of the entire device from the bottom, a cyclic process of extraction, which leads to poor performance and difficulty lifting device in the presence of waves on the water surface.

The closest in technical essence and the achieved result is a device for the extraction of minerals from the seabed of the continental shelf, including transport is owocow pipe for supply of minerals and piping for supplying coolant thus, a transport pipe for the supply of minerals in the lower part is made with a bell, and the rest placed in a hollow tube and is located coaxially with it, and the pipe for feeding refrigerant is made in the form of a pipe auger, with the possibility of extension. The screw can be made for example of polymer (EN 115410 U1, IPC E21C 50/00 from 07.11.2011, published on 27.04.2012).

This invention has several disadvantages:

the air gap between the walls of the outer and distributor pipes leads to corrosion;

- the formation of ice between the pipe auger and the wall of the transport pipe may lead to stoppage of the mining process.

The task of the technical solution is to simplify the extraction of minerals from the seabed of the continental shelf, improving performance and minimizing pollution during operation of the device.

This is achieved in that the device for the extraction of minerals from the seabed of the continental shelf, including the transporting pipe for the supply of minerals, coaxially located in the hollow tube, the lower part is made with a socket, a pipe for feeding refrigerant is further provided with a piping for supplying coolant evenly distributed around the perimeter of the hollow tube, the walls of the socket and in addition set the Lenna racks socket, this hollow tube at the level of the racks of the socket, and the inner walls of the uprights of the socket is provided with perforations, and at the level of the bell hollow tube has a vertical slot that the top and bottom provided with plugs, the upper part of the uprights of the socket is also provided with plugs, and the ends of the hollow tubes and racks socket located in the reservoir, made with particular reference in the form of a cone.

Placement of pipelines to supply the refrigerant in the hollow tube, the walls of the socket and the posts of the socket, to avoid contact of pipelines to supply refrigerant from the external environment, thereby preventing namerzanie them ice and fine particles of minerals.

Sharpening of the cone ends of the hollow tubes and racks socket located in the reservoir, contribute the least resistance with the introduction of the working body in the ground downhole space.

Perforation of the walls of the hollow tube and the inner walls of the uprights of the socket allows the refrigerant passing through them, evenly distributed throughout the depth of the downhole space, which, in turn, provides quality freezing fossil.

The slots of the hollow tube is made to ensure the smooth passage formed in the underwater bottom grunwaldova bodies in the conveying pipe.
