FIELD: mining, particularly to produce ore and rock materials, for instance building materials.
SUBSTANCE: mining rig comprises pontoon with suction head having sludge receiving means, as well as crane for sludge receiving means lifting and lowering installed in front pontoon part. Sludge receiving means is lifted and lowered by suction head rotation about axle connected to pontoon. Rig comprises sludge line connected to sludge channel of suction head. The pontoon has U-shaped cross-section and is provided with additional crane arranged in rear part thereof. The suction head is made as downhole hydraulic tool having string composed of two parts in length direction. The parts are pivotally connected one to another. The string is arranged on pontoon so that the parts may be lowered in series. The cranes are portal. The axle is located in rear or front pontoon part.
EFFECT: possibility of mining work performing at variable development depth.
