  • Publication number: 20180195391
    Abstract: 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.

  • Publication number: 20170198581
    Abstract: An extraction and retrieval apparatus for highwall mining equipment which includes a mining head engaged with and proceeded by a series of push beams The apparatus includes a retriever platform having wing braces for bracing the retriever platform against a mine highwall and a hydraulic assembly is mounted on the retriever platform and includes at least a spaced pair of stop blocks securable to the retriever platform at multiple different positions therealong. The hydraulic assembly further includes a pull beam slidable along the retriever platform and having a connection for connecting the pull beam to an outer most exposed push beam of the mining equipment. A spaced pair of hydraulic cylinders are disposed between the pair of stop blocks and the pull beam for pulling a connected mining push beam together with attached mining equipment from the mine shaft.

  • Patent number: 9617705
    Abstract: A retainment wall for underground horizontally extending mine shafts wherein a spaced vertical series of horizontal support ribs are secured to one or more upright supports that are secured in the mine shaft between the side walls thereof. Porous material covers and is secured to the forward retaining face of the wall structure. If the retainment wall structure is to be used as a fill retainment barrier the porous material is spray coated with a settable sealant which covers the forward face of the wall structure and the perimeter thereof to seal off the mine shaft.

  • Publication number: 20130051931
    Abstract: The present invention provides cambered impact resistant lagging roof panels for an arch support assembly which is designed for withstanding the effects of rock bursts in an underground mine. The impact resistant panels are aligned in a parallel series with their cambered faces facing upwardly and positioned transversely between adjacent sets of steel arch supports of the assembly. The impact resistant lagging panels are constructed as C-shaped metal channels with their channel openings facing downward. The panels are retained between adjacent beams under compression.

  • Patent number: 8371658
    Abstract: A mine rib support for bracing a vertical mine rib disposed between a mine floor and a mine roof. The support includes an elongated upright and continuous telescopically expandable support having a preset curvature. The member is longitudinally expanded for engaging the mine floor and the mine roof under compression with the curvature facing towards the mine rib. A support plate is laterally extended from the support member into compression engagement with the mine rib, thereby prestressing the support for support of the mine rib.

  • Publication number: 20120282041
    Abstract: An arch support assembly for withstanding the effects of rock burst in underground mines, which includes a spaced aligned series of arch supports, each support having a spaced pair of upright side support columns with an upwardly cambered cap beam arch having opposite ends therefore transversely meeting and secured respectively to the upper ends of the side columns at an obtuse angle. The arch supports are rigidly tied together and provided with a roof supported by the cap beams to provide in combination an arch support assembly.
