Abstract
A mine stopping installed in a mine passageway includes a plurality of elongate panels extending generally vertically in side-by-side relation from a floor to a roof of the passageway to at least partially close the passageway. A generally horizontal elongate brace extends generally between the walls of the passageway adjacent to the panels. A generally vertical column extends from the floor to the roof and is adapted for reinforcing the brace. Braces and anchor beams for stoppings are also disclosed.
Claims32
A mine stopping installed in a mine passageway having a floor, a roof and opposing walls comprising:
- a plurality of elongate panels extending generally vertically in side-by-side relation from adjacent the floor to adjacent the roof of the passageway to at least partially close the passageway;
- an elongate brace extending generally horizontally between the side walls of the passageway adjacent to the panels;
- and
- a generally vertical column extending from the floor to the roof for reinforcing the brace.
A mine stopping installed in a mine passageway having a floor, a roof and opposing side walls comprising:
- a stopping wall having a lower end adjacent the floor of the passageway;
- and
- a generally horizontal anchor beam secured to the floor of the passageway and positioned adjacent the lower end of the stopping wall for inhibiting movement of the stopping wall under a transverse load applied to the stopping.
A mine stopping installed in a mine passageway having a floor, a roof and opposing side walls comprising:
- a stopping wall having an upper end adjacent the roof of the passageway;
- and
- a generally horizontal anchor beam secured to the roof of the passageway and positioned adjacent the upper end of the stopping wall for inhibiting movement of the stopping wall under a transverse load applied to the stopping.
A brace for reinforcing a mine stopping system against deflection when the system is under load, the stopping system being installed in a mine passageway having a floor, a roof and opposing side walls, the brace comprising:
- a chord having opposite ends adapted to be secured to respective side walls of the passageway adjacent the stopping;
- at least one structural member having at least one end secured to the chord and adapted to extend generally outwardly away from the stopping when the brace is installed adjacent the stopping;
- and
- a support connected to the at least one structural member and having an end adapted to engage the floor or the roof of the mine passageway for supporting the brace.
A brace adapted to extend between opposite side walls of a mine passageway comprising:
- a central beam;
- and
- at least one slide member connected to the central beam and adapted for extensible movement relative to the central beam whereby the brace has a variable length;
- the central beam being I-beam shaped and the at least one slide member being channel shaped for mating engagement with the central beam.
A brace for reinforcing a stopping wall in a mine passageway comprising:
- a central beam;
- at least one slide member slidably connected to the central beam to provide relative movement therebetween whereby the brace has a variable length;
- at least one securement member fixed to the central beam and adapted for connection to the stopping wall, the securement member including an extensible member slidably connected to the securement member to provide relative movement therebetween;
- and
- a coupling connecting the slide member and the extensible member.
