The main shortcoming of this facility is that they are not used to erect linings in mines - are reversible, which leads to drilling and tensioning processes from ^ e wurdonjbQi which is not a definite and Konauan> .er Bauia between the outer periphery of the press member and the dismantling walls is obtained

In addition, when the linings are pressed in a longitudinal direction, the execution of the reinforcement of the linings is more difficult, as considerable shifts (Vei'set tongues) of the reinforcement take place in the course of the pressing.

Attempts have been made to develop facilities su which accomplish the pressing of the lining in the radial direction -
