FIELD: mining.SUBSTANCE: device comprises a delivery pipe for supply of minerals designed from top to bottom with a bell and a pipeline for coolant supply. The delivery pipe is designed as variable section pipe with formation of alternating cylindrical compartments with inlets and outlets, and the top parts of some compartments are arranged with inclination as cross-lying with reference to other compartments, and the lower parts of compartments are designed conical, interconnected with coolant supply pipelines. Outlets of compartments are located from inlet holes at the distance necessary for passing and maintaining of soil and ice bodies in a suspension provided that: L?3·d, where L - is the distance between inlets and outlets of compartments, d- maximum diameter of soil and ice bodies.EFFECT: improvement of efficiency of production of minerals from continental shelf.1 dwg |
