Publication number: 20180195391Abstract: A pumpable mine ventilation stopping wall structure comprised of a pumpable bag having spaced walls of generally parallel nonporous and flexible sheets with the sheets retained in spaced relationship with spaced flexible cross ties. The perimeter of the spaced walls may be closed off with a permeable mesh having a mesh size which will permit restricted flow of cementitious grout therethrough for sealing the wall structure to surrounding rough mine faces. The bag is provided with at least one grout fill port for filling the bag by pumping cementitious grout into the bag.Type: ApplicationFiled: February 20, 2015Publication date: July 12, 2018Inventors: Joseph P. Bower, John J. Breedlove, Erik Denver, Steven S. Fleagle, Tyler Proffitt

Patent number: 9200815Abstract: A ventilation ducting arrangement includes a flexible conduit having an inner surface defining a channel carrying a flow of air. First connectors are aligned in a length direction along a length of the inner surface of the conduit. Second connectors are aligned along the length direction. Each of the second connectors has a position along the length direction that is the same as a position of a corresponding first connector along the length direction but that is diametrically opposed to the position of the corresponding first connector relative to a circumference of the inner surface. Each of a plurality of fastening devices interconnects a respective one of the first connectors and a respective one of the second connectors such that a distance between the interconnected first connector and the interconnected second connector is limited by a length of the fastening device.Type: GrantFiled: August 24, 2012Date of Patent: December 1, 2015Assignee: ABC Industries, Inc.Inventors: Steven S. Fleagle, Kevin J. Carson

Patent number: 8246276Abstract: A pumpable inflatable crib bag assembly for supporting a mine roof which includes a generally cylindrical bag having top and bottom ends for retaining and confining a liquid settable grout to be pumped into the bag. The bag further includes an inner generally cylindrical mesh reinforcement disposed within and generally coextending with the bag. This generally cylindrical mesh reinforcement is spaced from an inner wall of the bag and is permeable to the liquid settable grout whereby the liquid settable grout may be pumped through a fill port into the bag to thereby fill the bag and encapsulate the mesh reinforcement. The liquid settable grout is pumped through a fill port which is adjacent the top end of the bag.Type: GrantFiled: February 28, 2011Date of Patent: August 21, 2012Assignees: ABC Industries, Inc., Heintzmann CorporationInventors: Joseph P. Bower, Steven S. Fleagle
