Abstract
In a method of sinking a mine shaft, the shaft is excavated and lined from a sinking stage and the previously excavated and lined shaft is simultaneously equipped from an equipping stage which is located above the sinking stage and which follows the sinking stage down the shaft. In this way, considerable time savings can be achieved in the sinking of the shaft.
