## Summary

The paper titled "Blasting Operations Using Different Initiation Methods in Deep Underground Mines" by Marcin Szumny, Piotr Mertuszka, Krzysztof Fuławka, Eugeniusz Koziarz and David Saiang explores the rock burst hazard associated with underground mining in Polish copper mines. As mining operations go deeper, the problem of rock bursts is expected to worsen due to seismic events that pose a significant danger to miners. To prevent rock bursts, controlled group blasting within potentially unstable roof strata is considered an active method. The authors investigate the effects of different initiation systems on rock burst prevention through the analysis of seismograms recorded during blasting works. Specifically, they compare non-electric initiation methods with electronic detonators that allow for precise delay times between explosive detonations in individual blastholes and mining faces. The study aims to determine if this approach can be considered a new blasting method for controlling rock bursts in deep mine conditions or if it can serve as a basis for modifying the currently used method. The findings suggest that recorded seismic events can be directly attributed to the effects of blasting works and that using electronic detonators enables better control over delay times which could potentially enhance rock burst prevention measures. The analysis of seismograms from selected blasting works differing in initiation systems provides valuable insights into the effectiveness of different methods. Overall, this research contributes to understanding and mitigating the rock burst hazard in underground mining operations by exploring alternative initiation methods and their impact on seismic events which could offer potential improvements for preventing rock bursts and ensuring miner safety in deep mines.
