Validation of safety in mixed-type mining: A case-study of Zapolyarny Mine

The article presents the research report on accident risk assessment of a pilot mixed-
type mining system in development of a flat ore body in Zapolyarny Mine using remote control load–haul–dump machines. The main accidents are identified (sudden rock collapses, breakdowns or misuse of mining equipment), and potential scenarios of accidents are discussed with their causes and stages identified. The defeating factors, the accident rate and the injury statistics are analyzed for the latest 10 years, and the tree of events is constructed with the probability assessment of negative consequences (damage or loss of mining machinery, traumatizing or death). The accident risk assessment is performed in each scenario using the frequency–gravity matrix, the individual risks are calculated and the rated values are compared with the allowable rate. The results show that the accident risks and the related damages in all scenarios analyzed are lower than the allowable level given the adopted safety control. Mining safety is provided at all mining stages in the pilot extraction block.
