Project: Black Panther Mine Shaft - Oaktown, IN
Customer: Black Panther Mining LLC
Contractor: Ambrose Construction
Project obstacles and solutions: The Black Panther Mines needed a fill product to firm up the ceiling and walls of their shaft tunnels. Normal fills would have to be compacted to provide stability. IMI poured 15,000 yards of imix Mine Grout. This product is self-leveling, self-consolidating and flowable. It was pumped over 2,000 feet into the shafts without any problems. The product had to work into all spaces without leaving gaps. That included plunging 400 feet vertical drops and horizontal spaces. The product covered and stabilized all the headers on arches, providing 400 psi strength. The product set up in 24 hours so construction of the shafts could continue.
