Abstract:
The invention relates to a method for introducing a vertical shaft underground and to a shaft driving machine set up particularly for performing the method, wherein a cutting wheel is rotated solely about a horizontal axis until a penetration trough having a predetermined penetration depth is formed, and the cutting wheel is then also rotated about a central vertical axis until a shaft foot is dug out to the penetration depth. A relatively high sinking rate is thereby achieved for the shaft.
