On Modelling the Reliability of Concrete Support for Underground Construction Considering the Impact of Chemical Erosion

Abstract

Ensuring the reliability of support in mine workings has always been one of the most important scientific and technical problems in mining. To ensure the normal operation of underground structures, it is necessary to apply special measures to maintain the support, providing increased stability of rock array. To one of the most important measures is to maintain the reliability of the supports in underground workings and objects of underground construction. The main method of research in this area is the modeling of the reliability of concrete support, as applied to various exogenous and endogenous factors of disturbance. The article provides theoretical provisions of research in physico-chemical processes of corrosion in reinforced concrete for modelling the reliability of structural elements of supports for underground construction objects.
