  • Preventing Controlling Flyrock with Blast Mats Shields ...

    Studies to try to more accurately predict the impact of flyrock in various blasting situations have proven costly and not yielded highly satisfactory results. While it is not currently possible to prevent the creation of flyrock itself, almost all flyrock injuries and fatalities, as well as flyrock damage to property, is avoidable when taking the proper precautions. Too often, people on mining ...
