Underground Limestone Mine Airblast Study

Collecting high-pressure airblast readings and providing site-specific data.

Lhoist

Lhoist required assistance with evaluating blast pressures at their developing underground mine to understand when underground infrastructure could be installed during the development process. Installing ventilation walls and underground infrastructure is important for an underground operation; however, this task cannot be started until the blasts have progressed far enough from the infrastructure locations to ensure that the infrastructure is not damaged.

RESPEC collected baseline airblast data at Lhoist during 1-week, on-site monitoring program. We compared the data to historical data that we had previously recorded in a similar mining operation. RESPEC also provided the results and comparison data to Lhoist in a technical report.
