    摘要: A mine stopping having a man door and door frame assembly in which the mine stopping comprises a plurality of elongate extensible and contractible panels extending vertically in side-by-side relation from the floor to the roof of a passageway in a mine. Each panel comprises a first elongate member constituting the lower member of the panel and a second elongate member constituting the upper member of the panel. Each of the panel members has a web and flanges at opposite sides of the web, one of the members having a telescoping sliding fit in the other. The assembly comprises a rectangular frame having top, bottom and side channel members, the door being hinged to one of these. The frame is mounted in an opening in the mine stopping without any fastening means between the frame and stopping panels thereby maintaining the extensibility and contractibility of the panels.

    摘要: A section of brattice is mounted on a centrally-wheeled cart. This brattice has a frame that permits the curtain section to be extended and retracted vertically, in order to reduce its height for movement and to adjust its height for engagement of the mine roof. Hydraulic jacks are used for vertical height adjustment. The upper curtain rod rail of the curtain incorporates a spring that is mounted between some spring-mounted posts. When the curtain is raised against the ceiling, the springs allow the top of the curtain to conform to unevenness in the ceiling level. By preference, the wheels are mounted on a yoke so they can be put down for moving the brattice section, and retracted when the brattice section is in place. Two jacks are additionally provided at the ends of the apparatus for extension against the roof when the cart is in place to act as anti-tipping braces for when the brattice section is extended up against the mine roof.

    摘要: This disclosure relates to a portable stopping for blocking crosscuts in mine entries to facilitate ventilation thereof. The stopping consists of a sheet of fire-resistant, gas impervious flexible material adapted to be extended across a crosscut between the roof, floor, and walls or ribs thereof. A frame structure is adapted to support the sheet in substantially airtight relationship across the crosscut. The frame carries elongated channel-like straps which are adapted to compress edge portions of the sheet against the roof, floor and side rib surfaces of the crosscut, thereby providing a substantially airtight seal about the perimeter of the sheet.

    摘要: The present invention relates to a sealing system, its uses and method of use for forming a seal against a surface, and in particular for plugging and sealing an orifice such as a road or railway tunnel to prevent or minimise the dispersion of hazardous agent(s) in an emergency scenario. The system comprises a frame (200) which can be orientated against a surface (50) of an orifice, frame (10) comprising a perimeter outer surface (180) through which pliant elements (40) can extrude, via apertures (22), following the initiation of a means (30) for providing an overpressure.

    摘要: A mine stopping panel is disclosed. The panel includes first and second channel-shaped panel members having a telescoping sliding fit one inside the other. An elongate end cap is fitted in the first panel member. One or more louver connections between the first panel member and the end cap hold the end cap against movement relative to the first panel member when an extending force is applied to the end cap tending to telescopically extend the first panel member relative to the second panel member.
