Substantiation of Geotechnical Risk Assessment Criterion for Mining Systems with Uncontrolled Caving of Ore and Surrounding Formations

Abstract

The high risk of technogenic accidents involving caving technologies due to the variability of the state of rock mass determines the parameters of variability taking into account geotechnical risks based on the knowledge of the rock mass obtained through continuous monitoring. The assessment of geotechnical risks in mining taking into account the increasing reliability of design data input obtained through mining exploration, additional research, and monitoring results can help promptly respond to possible dangers and their consequences. The suggested geotechnical risk assessment criterion helps determine the level of danger at every stage of block caving implementation and promptly develop actions to prevent these risks and reduce their dependency on the external and internal environment factors.
