FIELD: mining. SUBSTANCE: method for opencast mining includes extraction of rock mass and its loading into transportation vessel. Transportation vessel has fixed point of suspension which is fixed to aerosupport in form of gas-filled vessel. Loaded transportation vessel is moved from loading point over quasi-horizontal trajectory under gravity. Then, it is moved over pendulum trajectory, first, by gravitation force up to passing the dead point, and further on, by inertia forces. Then, transportation vessel is pulled to discharge point over quasi-horizontal trajectory. EFFECT: higher efficiency. 3 dwg
