Abstract
A form installed in a mine for making a permanent mine stopping or seal of pourable and hardenable material includes first and second form walls in spaced, generally parallel relation to one another. Each of the first and second form walls includes a portable wall section including a plurality of elongate upright panels secured together in general parallel, side-by-side relation. Each panel includes a lower panel member having a lower end and an upper panel member extending from the lower panel member and having an upper end in substantial engagement with a roof of the mine passage.

A form installed in a mine for making a permanent mine stopping or seal of pourable and hardenable material comprising:
- first and second form walls in spaced, generally parallel relation to one another,
- each of said first and second form walls comprising a portable wall section,
- each wall section comprising a plurality of elongate upright panels secured together for transport as a portable assembly in which the panels extend in generally parallel, side-by-side relation, each panel including a lower panel member having a lower end and an upper panel member extending from the lower panel member and having an upper end in substantial engagement with a roof of the mine passage.
A form installed in a mine for making a permanent mine stopping or seal of pourable and hardenable material comprising:
- first and second form walls in spaced, generally parallel relation to one another,
- at least one of said first and second form walls comprising a plurality of portable wall sections,
- each of said wall sections comprising a plurality of elongate upright panels secured together for transport as a portable assembly in which the panels extend in generally parallel, side-by-side relation, each panel including a lower panel member having a lower end and an upper panel member extending from the lower panel member and having an upper end in substantial engagement with a roof of the mine passage.
A method of installing a form for a mine stopping at a site in a mine passage defined by a floor, roof and opposing side ribs, said form being of the type comprising first and second form walls, each of said first and second form walls comprising a portable wall section including a plurality of upright panels secured in adjacent side-by-side relation, each panel including a lower panel member having a lower end and an upper panel member extending upward from the lower panel member, said method comprising
- a) positioning the wall section of the first form wall transversely with respect to said passageway,
- b) positioning the wall section of the second form wall generally parallel to and spaced from the wall section of the first form wall to define a cavity for receiving pourable and hardenable material,
- c) extending the upper panel members relative to the lower panel members to bring the upper panel members into pressure engagement with the roof of the mine passage, and
- d) securing the upper panel members relative to the lower panel members in extended position.
