Ground Condition Analysis and Risk Mitigation
In an irregular event, a cavity appeared after a blast on surface at a South African open pit Iron Ore operation. To mitigate subsequent risk the mine needed to understand the ground conditions and cavity dimensions, specifically how far the cavity extended and to ultimately understand potential reasons for the cause for the cavity. The mine also needed to collect adequate data to determine if it was safe for mine personnel to proceed with mining activities in the direction of the cavity specifically on top of the bench where drilling had taken place.
