Abstract

Loading-deformational characteristics of rocks in
the shaft contour depending on their strength variation on a time basis are considered in the article. In
terms of the researches analysis of rocks strength
properties and rock pressure manifestation in subsurface mine workings both the range of rock mass
strength decrease and pace of this variation are determined. The obtained results permit to estimate the
rocks loading-deformational characteristics in the
shaft contour and to define the shafts’ support parameters in the IV class conditions of sedimentary
rocks by well-grounded way.
