Abstract
In underground mining, rock pillars are frequently utilized to provide support within
the deposit. Many of these pillars, either due to their geometry or the stress field acting upon them, experience inclined loads.
Hence, this study aims to develop local models to analyze the impact of inclined loads on the stability of rock pillars.
The models were created using FLAC3D for various types of pillars, and the Hoek & Brown failure criterion was applied, employing equivalent parameters to simulate medium quality rock.
Through these models, the influence of inclined loads on pillars and the width-height ratio were examined.
The results indicate that pillars exhibit reduced resistance to inclined loads with a shear component, while the strength increases with an increased width-height ratio.
