FIELD: technology of mineral mining by opencast methods or by underground mine workings of vertical, inclined or horizontal locations. SUBSTANCE: method includes driving of working in mass of mineral and installation of hollow guide support carrying rock breaking unit into said working, layer-by-layer working of face in circular and radial directions, loading and haulage of rock to receiving chamber, ore introduction into containers, moving of containers over hydraulic main line where they are given positive buoyancy, unloading of containers in atmosphere medium, returning of containers after unloading over main line in gas medium with braking of empty container by front resistance and air flowing-over from bottom upward along its walls and walls of main line. As face advances, rock breaking unit is moved along generating line of guide support to face. District of rock mass mining is selected in circular and radial directions depending on content of useful mineral in ore mass. EFFECT: higher efficiency of all operations forming process line of offered method of mineral mining. 5 dwg |
