NIOSH Releases Software to Improve Mine Blasting

Mines can now reduce the risk of post-blast ground falls with the DRIFT software, which helps engineers to create more effective
blast designs.

DRIFT was developed by the National Institute for Occupational Safety and Health (NIOSH) Mining Program to help reduce the risk of ground falls, which remain a serious threat to the safety of miners. Poor blast design can lead to loose or damaged rocks in the roof and at the ribs of drifts when the force of a blast extends beyond the target area. Scaling, excessive overbreak, and damage to supported ground all pose a risk of disabling injuries and fatalities to miners after blasting is completed. Engineers rely on good design practices to limit damage to areas surrounding the blast zone. Current controls address this problem through perimeter blasting, but these controls lack precision. DRIFT, an acronym for Design method to Reduce risk of Injury from ground Falls Technique, combines perimeter blast designs with a buffer row to further reduce ground falls that occur from perimeter damage. DRIFT enables engineers to create a conceptual blast design by coordinating perimeter and buffer rows for blasting.
