FIELD: mining, particularly dredgers or soil-shifting machines used for open mining of bedded deposits having low dip angles and characterized by solid surrounding rock.
SUBSTANCE: mining-and-hauling device comprises basic chassis with blade, gas turbine engine, gas pipeline having variable cross-section with injector nozzle and loading opening. The device is provided with rotor thrower and active mechanical ripper. Active mechanical ripper teeth are spaced apart along the full working zone of the blade and provided with air hammers. Compressed air is supplied to air hammers from high-pressure compressor of gas turbine engine. Gas turbine engine has two shafts and is adapted to drive rotor thrower by free engine shaft.
EFFECT: reduced specific power inputs for solid rock cutting and extended field of application of continuous deposit development technology.
