THE REGULARITIES OF DEFORMING THE SHAFT’S ROCK WALLS DURING THE PROCESS OF FACE ADVANCING IN THE CONDITIONS OF ROCK MASS LIMIT-EXCEEDING STRESSED- DEFORMED STATE

Abstract

In terms of the results of performed natural researches of the shaft’s rock mass walls stresseddeformed state in the process of its construction according to combined technological scheme, the
mathematical model of dependence of the correcting
lowering multiplier α* is obtained from the distance
relation till a face to radius of the working in rough.
The comparative analysis of α* change in the rock
mass in the conditions of elastic deforming as well
as in the rock mass being in an limit-exceeding
state is carried out.
