Abstract: In developing an underground mine a mine shaft 80 is formed by excavating earth and removing excavated material from the shaft 80 by a material transport system comprising skips 36 movable up and down on skip guides within the shaft. Tunnels 82 are launched from a bottom part of shaft 80 by excavating a cavern 81 in which a tunnel boring machine is assembled and operated to bore the tunnels 82. Material from the tunnel excavation is transported from the tunnels via conveyor 87 to the material transport system established within the shaft during formation of the shaft which is operated to transport that material to an earth surface region.
