Method of winning reserves in the vicinity of a shaft and shaft lining for carrying out this method

摘要

The essentially vertically orientated shaft 1 passes through a seam 5. At least one landing is attached to the shaft 1 at a distance from the seam 5. The face layout in the seam 5 is of two-sided configuration. A shaft safety pillar is arranged transversely to the landing axis in the seam 5. The shaft axis 4 pierces the shaft safety pillar in the seam 5 inside the face length. In the shaft area, the width of the shaft safety pillar corresponds approximately to the shaft diameter. Provided in the seam area is a special shaft lining 11 which can be shortened under rock pressure in its extension perpendicular to the stratification and consists of rings 12 connected to the rock 15 and parallel to the bed. The rings can be designed as concrete rings. But steel rings of channel-shaped cross-section are also conceivable. Furthermore, a combination of concentrically nested ring sections is also conceivable, which are separated from one another by a vertical sliding layer and in each case consist of three vertical layers with compression behaviour differing from one another. <IMAGE>
