description FIELD: mining industry, as well as hydraulic, road, agriculture and other building, particularly to perform open cast mining and other woks by rock loosening. ^ SUBSTANCE: method involves obtaining information concerning main and structural-and-strength rock properties on the base of estimation of data of primary and post-authorization prospecting, as well as production prospecting; detailed rock zoning to separate production blocks and unit blocks characterized by uniform rock at borders thereof; writing computer program; automatically loosing rock of each unit block by most effective method, namely by mechanical, pneumatic, blast drilling or physical one performed with the use of all-purpose mobile rig tools. Above rig includes computer system, device provided with one, two or three replaceable teeth, with plate-like metal pins and with hydraulic cylinders. The rig also has device adapted to create holes in unit block and wedge out thereof, drilling device and charging device, laser charge initiation system, local shelter with damping means, device for rock cutting by applying pressurized air and impacts to rock and auxiliary excavation device. ^ EFFECT: increased efficiency of rock preparation for further cutting and loading and for solid mineral field development as a whole. ^ 1 dwg
