METHODOLOGY FOR EFFECTIVE DETERMINATION OF ROCK JOINTING IN CALCULATION OF OPEN PIT EDGES
This paper is intended to increase the reliability of measuring the stability of open pit edges by developing a methodology for remote determination of rock jointing. The study employed a number of methods: analysis and summarization of results of previous studies, including those presented in regulatory and methodological documents; instrumental studies in field conditions, mathematical processing of experimental data results, computer modeling of stress strain behavior of the near-edge massif. The paper proposes the scheme to account for rock jointing by using digital photo survey in order to specify the stability parameters of edges, with the remote method to study jointing tested at the Novosergeyevskiy and Pechurki open pits. The practical value consists in developing calculation methods for stability of open pit edges by accounting for rock jointing. The obtained results can be used at design mining companies, educational institutions and at open pits (quarries), as well as at specialized organizations studying rock jointing properties.
