Abstract
A mine stopping device and method of constructing same utilizing a plurality of laterally spaced substantially vertically disposed support members extending from the floor to the ceiling of a mine tunnel with a wire mesh screening secured thereto and extending substantially across the entire cross sectional area of the mine tunnel, and a plaster applied to the wire mesh to form a substantially air tight wall in sealing engagement with the walls, floor and ceiling of the mine tunnel. An inspection door can be provided in the mine stopping with an adjustable hinge which permits the door to be realigned with the door frame if the frame is distorted due to shift in the roof of the mine.
Claims5
A permanent mine stopping device for use in an underground coal mine tunnel or the like, comprising:
- a plurality of individual self-supporting vertically disposed support members each being laterally spaced from adjacent members said plurality of support members being positioned so as to extend across the width of the mine tunnel being stopped;
- each of said support members having a top and bottom end and adjustment means for vertically adjusting the length of said support member so that the length of each of said support members can be extended until the top and bottom ends respectively come into engagement with the roof and floor of the mine tunnel being stopped so that said support members provide support for the roof of the tunnel;
- wire mesh secured to the individual support members and extending over substantially the entire cross-section of the tunnel;
- plaster applied to the wire mesh and having its outer periphery in substantially air-tight sealing engagement with the walls, floor and ceiling of the mine tunnel, whereby air is prevented from flowing through the tunnel in which the device is placed, each of said support members being comprised of upper and lower members, said upper and lower members being connected together by said adjustment means so as to be movable toward and away from each other, and wherein each of said upper and lower members are provided along their length with a plurality of apertures so as to permit the wire mesh to be secured to said support members.
