ANALYSIS OF THE UNDERGROUND ROOMS STABILITY (LATERAL DRIFTS) AND CALCULATION OF THE LOADING OF SAFETY PILLARS IN UNDERGROUND MINE "BATURINKA"

Abstract

The stability analysis was performed on the model of underground rooms of rectangular cross-section on the example of the underground mine ,,Baturinkaʻʻ. Geotechnical data of bauxite and surrounding rocks were used for the mentioned research. The analysis of stability was performed according to the Hoek-Brown criterion of rock mass failure and data processing was performed in the software program Phase2. In order to meet the set criterion of value of safety factors (Fs), when dimensioning safety pillars, used calculation of rock mass loading, in the form of panel.
