The paper presents a patented and copyright protected concept of constructing a shaft lining that goes through salt rock massif having strong rheological properties and being susceptible to leaching. In the case of salt layers, especially on significant depths (over 1000 m) the relative convergence of the heading contour may amount even to 0,18 m/year. That results in the fact that any other method of securing the shaft lining, e.g. by making it flexible, will not be sufficient to ensure the stability of the shaft...
