Abstract: In forming a mine shaft for an underground mine, earth excavated by a boring machine (21) is transported upwardly by handling unit (22) to a transfer station (33) where it is transferred into skips 36 which are raised and lowered along skip guides 38 within the shaft hole (19) for transport of the excavated material to an earth surface region. Transfer station (33) is moved downwardly as excavation progresses.
