A method for underground mining in a rock body include drilling one or more service boreholes from at least one surface location into a subsurface rock body. A plurality of multilateral blast holes is drilled, branching from at least one of the one or more service boreholes into the subsurface rock body. The plurality of multilateral blast holes are each loaded with one or more explosive charges and one or more detonators. The one or more explosive charges and the one or more detonators are inserted from surface. The one or more explosive charges is detonated wirelessly to fragment the subsurface ore body. Fragmented rock is extracted via the one or more service boreholes, to surface.

A variable length guide system for guiding a conveyance along a mineshaft, the variable length guide system extending downwardly from a work stage and being extendable or retractable to accommodate changes in distance between the work stage and a lower region of a mineshaft.

A method of moving a component or a material to and within a level of a shaft boring system. The shaft boring system is positioned within a shaft and the method comprises lowering the component or the material inside a cage into the shaft and to a level of the shaft boring system. The method further comprises suspending the component or the material from a transport system within the level of the shaft boring system. In addition, the method comprises moving the component or the material within the level of the shaft boring system using the transport system. The component is a component of the shaft boring system and the material is a material for forming the shaft boring system.
