Workers prepare slope for trim blasting
Material dislodged from blast
Explosive Charges Detonated on Western Slope
CHATTANOOGA, Tenn. – Crews with contractor Charles Blalock & Sons today set off explosive charges on the western portion of the slope in order to remove a seam of unstable rock as part of the overall remediation plan. The contractor drilled a series of holes through the unstable rock layer to the desired depth, set off the explosive charges, and successfully exposed a stable layer of rock that is less susceptible to future slides. The contactor plans to continue working from the west side of the slope to the east with drilling and trim blasting operations and will begin hauling away slide debris this week as work progresses to the east. The larger debris will be broken into a manageable size using a hoe-ram, loaded on to dump trucks and removed from the site.
Hand scaling, drilling, and trim blasting operations are expected to continue through Sunday as weather permits.
