FIELD: mining.
SUBSTANCE: invention refers to extraction of valuable minerals from hard and high viscous sand-clay rocks at open development of auriferous gravel deposits. The hydro-transporting pressurised system with the static cavitator consists of a tube bend and reflection elements. Elements of narrowing, elements of expanding and a reducing ring are located inside the straight section of the tube and are made complex from parts, the interior surfaces of which form conic surfaces with gaps. Tops of formed conic surfaces are turned to each other, while the reflection elements are conjugated with thrust collars and assembled before the narrowing elements and after the expanding elements down the hydro-stream motion; they are oriented along the axes of symmetry and axes of gaps of the narrowing and expanding elements of the static cavitator; the reflection elements are made in form of a right triangle, acute angles of which are oriented counter the hydro-stream motion before the narrowing elements, while they are oriented down the hydro-stream motion after the expanding element.
EFFECT: intensification of process of directed destruction of sand-clay rock by means of hydro-mechanical cavitation at pressurised hydro-transporting to systems of deep processing.
