Zubkov A.V., Sentyabov S.V., Biryuchev I.V. The effect of changes of horizontal stresses in rock mass on shaft supports

Abstract

This article presents results of the research and calculations performed by the Institute of Mining of the Ural Branch of the Russian Academy of Sciences in the underground mine of Gaisky Ore Dressing Plant. The observed phenomenon of expansion and contraction of the Earth occurring in sync with easily tracked changes of the Sun’s size requires further examination and precise definition of correlation dependences. The article shows calculations and measurements of stresses in shaft sup-ports which depend not only on the physical and mechanical properties of solid rock, but also on the time of shaft sinking and stops in the construction of the support for a period while concrete gained its full strength. There is a risk of destroying the integrity of shaft supports.

Keywords

Conditionally permanent tectonic stresses, stress-strain state of the shaft supports, astrophysical stresses, concrete support, rock mass.
