Application of professor D. Lobshire’s geomechanical classification for in-depth zoning of the board of the Amantaytau mine

This study presents a comprehensive analysis of the physical and mechanical properties, structural disturbance, and stress-strain state of the rock mass in the Amantaytau deposit, situated in the southwestern part of the Muruntau ore field. The geomechanical classification rating (MRMR), as proposed by Prof. D. Lobshir, is employed to evaluate the geomechanical state and establish a zoning framework for the deposit’s quarry in terms of depth. Furthermore, preliminary recommendations for stable slope angles are provided as an initial approximation based on the conducted investigations. The findings of this study contribute to a better understanding of the geomechanical characteristics of the Amantaytau deposit and offer valuable insights for optimizing slope stability in quarrying operations.
