SRK Master Class: Talk 7 - Underground Case Study: Russian and international experience in assessing the Open Stope Stability

Underground Case Study: Russian and international experience in assessing the Open Stope Stability.

The Ridder-Sokolny Mine was used as an example to demonstrate the Mathews graph method for stope stability assessment. The method is based on the processing of the collected historical and recent data related to open stope parameters with different stability conditions. The object classification methods are used to determine the Stable, Unstable and Caved conditions based on the collected field data. The established stope stability condition is used then to determine the allowable parameters of the open stopes at which the hanging wall of the void area will remain stable.
