Abstract

Bozymchak is a copper mine in Kyrgyzstan that is transitioning from open pit to underground mining using sub-level caving method (SLC). Longitudinal SLC mining is planned to continue downward from the base of the existing open pit until mine closure. Several geotechnical investigations were completed to understand ground conditions in the deeper areas of the deposit. These included diamond core drilling, mapping of capital developments and the modelling of major geological structures. Three-dimensional (3D) stress-strain analysis was completed using the finite element method (FEM) to identify areas of risk forming from high stresses in response to SLC extraction. This paper briefly describes the stress-strain modelling, risks identified with the SLC sequence, and planned control measures to mitigate those risks.
