Abstract

The influence of jointing on the stability of adjacent rock mass is analyzed using the coefficient of structural weakening and the joint spacing. The gravity–tectonic stress field of ore bodies in Gornaya Shoria, including the azimuth of the principal horizontal stresses is characterized. The laboratory tension tests of combinations of support systems as well as the small-scale extension tests of rock bolts made of different materials are discussed. The framework for a multi-factor digital model of safe and efficient support design for iron ore mines in Gornaya Shoria is based on the stability assessment of adjacent rock mass in terms of jointing and stress state.
