Abstract
A barricade wall is provided that is easily and rapidly customizable in a mine depending on the requirements of the particularly open area. The barricade wall can be customizable depending on the size and spatial requirements of a particular open area in a mine. Further, the top beams of the barricade wall can be elongated or shortened, depending on the requirements of the open area in the mine. The barricade wall has a first rigid wall section with spring loaded wall extensions attached to the wall section.
Claims18
A barricade wall assembly comprising:
- a wall structure including:
- a central wall section;
- at least one wall extension located at an edge of the central wall section, the wall extension being movable between a retracted position in which a dimension of the wall structure is reduced and an extended position in which the dimension of the wall structure is increased;
- and
- at least one biasing mechanism connecting the at least one wall extension to the central wall section, the biasing mechanism spring biasing the at least one wall extension towards the extended position.
A method of installing a barricade wall structure in a passageway, wherein the barricade wall structure includes a plurality of wall extensions secured to one or more of top and side edges of the central wall section, the wall extensions each being movable between a retracted position and an extended position and being spring biased towards the extended position, wherein in the extended position the wall extensions cause the barricade wall structure to have a larger coverage area than in the retracted position,
- the method comprising:
- restraining the wall extensions into their respective retracted positions against the spring biasing;
- positioning the barricade wall structure, with the wall extensions in the retracted position, at least partially across the passageway;
- and
- after positioning the barricade wall structure, releasing the wall extensions from their respective retracted positions to cause the wall extensions to move under force of the spring biasing to the extended position so that the barricade wall structure extends further across the passageway than when the wall extensions were in the retracted position.
A barricade wall assembly comprising:
- a wall structure including:
- a central wall section including one or more rigid panels and mesh structures secured to a surface of the one or more rigid panels to receive a concrete coating, and a pair of skids on an opposite facing surface of the one or more rigid panels than the mesh structures;
- at least one wall extension located at an edge of the central wall section, the wall extension being movable between a retracted position in which a dimension of the wall structure is reduced and an extended position in which the dimension of the wall structure is increased.
