Abstract
A mine stopping installed in a mine passageway includes a rigid wall extending across the passageway to close the passageway. The wall includes a first wall section extending from one side of the passageway at a first angle and a second wall section extending from an opposite side of the passageway at an oblique angle relative to the opposite side such that the wall sections are arranged in a non-coplanar, non-parallel relationship with respect to one another. A method of installation is also disclosed.
Claims5
A mine stopping installed in a mine passageway comprises:
- a rigid wall extending across the passageway to close the passageway, said wall comprising a first wall section extending from one side of the passageway at a first angle and a second wall section extending from an opposite side of the passageway at an oblique angle relative to the opposite side such that the wall sections are arranged in a non-coplanar, non-parallel relationship with respect to one another.
A method of installing a stopping in a mine wherein the stopping comprises a plurality of elongate extensible panels adapted to extend from a floor to a roof of a passageway in the mine, each panel comprising a lower panel member adapted for engagement of its lower end with the floor and an upper panel member adapted for engagement of its upper end with the roof, the method comprising:
- positioning a first of said extensible panels at a first angle relative to sides of the passageway,
- positioning a second of said extensible panels at a second angle relative to sides of the passageway,
- forcing the upper end of the upper panel member of said panels into engagement with the roof and the lower end of the lower panel member of said panels into engagement with the floor,
- wherein at least one of said first and second angles is oblique with respect to the sides of the passageway.
