The shaft lining, in particular for the lining of deep shafts sunk by the freezing process in unstable rock, essentially consists of a load-bearing, sliding inner lining which is surrounded by a steel casing and is arranged at a radial distance inside an outer lining while forming an annular gap filled with a sliding liquid. To relieve the large axial pressure forces, buoyancy elements (4) are provided at the outer wall of the inner lining (2) (Fig. 1). <IMAGE>
