Conducting a drill-and-blast audit in an underground gold mine.
Kinross Chirano Gold Mine
Kinross Chirano undeground gold mine uses a shrinkage stoping mining method partnered with a modified backfill process. Kinross requested a complete drill-and-blast audit to address poor fragmentation, drillhole collapse, and blast quality. Kinross also requested that a training program be developed for their staff based on the findings of the audit.
RESPEC partnered with Lusk Consulting to conduct the drill-and-blast audit at Kinross. RESPEC used drillhole deviation survey equipment, seismographs, the velocity of detonation equipment, photograph fragmentation, and borehole camera surveys to audit the drill-and-blast operations thoroughly. RESPEC’s findings on the project were developed into a comprehensive training program and a continuous drill-and-blast improvement program.
