Cavability Assessment in Narigan IIX Mine Using Empirical and Numerical Methods

This paper introduces a comprehensive study of the cavability of rock mass in the Narigan IIX mine through the application of empirical and numerical methods. The assessment of caving requirements is crucial for ensuring the safety and efficiency of underground mining operations. First, this study integrates all needed data with field investigations and laboratory tests used in empirical approaches and advanced numerical modeling to evaluate the cavability of the rock mass. After that, employing Laubscher's chart and Mathews's stability graph, rock mass was classified, and the minimum required HR was calculated for all Narigan IIX mi tectonic blocks. On the other hand, to evaluate empirical approach results, endeavor to create a beneficial model by DEM and obtain more insights about the caving process. The findings from both empirical and numerical analyses led to a minimum HR equal to ۱۸ m with a square shape for undercut and the cave angle near ۷۰ degrees. The results of this study are anticipated to contribute to improved mining practices and enhanced safety measures in similar geological settings.
