Abstract
This invention is directed to a mine roof support set including a plurality of nested containers. Each container in the set has a progressively smaller cross-sectional dimension to allow the containers to be nested one within the other. The plurality of containers can be nested during transportation of the mine roof support set to a mine site. The containers can be separated at the mine site and filled with a load-bearing material. The containers filled with the load-bearing material are placed with their longitudinal axis between a mine roof and a mine floor.

A mine roof support set comprising a plurality of containers, each said container comprising a closed bottom end, an open top end, and a sidewall that defines a cross-sectional dimension and having a longitudinal axis, each said container being adapted to be placed with the longitudinal axis extending between a mine roof and a mine floor oriented such that the top end of each container is distal from the mine floor and the bottom end of each container is distal from the mine roof, wherein each container in the set has a progressively smaller cross-sectional dimension to allow the containers to be nested one within the other such that the closed bottom end of each nested container is enveloped by the open top end of another container.
A mine roof support system comprising:
- (i) a plurality of containers, each said container comprising a closed bottom end, an open top end, and a sidewall that defines a cross-sectional dimension and having a longitudinal axis, each container being adapted to be placed with the longitudinal axis extending between a mine roof and a mine floor oriented such that the top end of each container is distal from the mine floor and the bottom end of each container is distal from the mine roof, wherein said containers have a progressively smaller cross-sectional dimension;
- and (ii) load-bearing material to be received within each said container.
A method of supporting a mine roof comprising:
- (i) assembling a plurality of containers, each said container comprising a closed bottom end, an open top end, and a sidewall that defines a cross-sectional dimension and having a longitudinal axis, each container being adapted to be placed with the longitudinal axis extending between a mine roof and a mine floor oriented such that the top end of each container is distal from the mine floor and the bottom end of each container is distal from the mine roof, wherein said containers have a progressively smaller cross-sectional dimension;
- (ii) filling said containers with a load-bearing material;
- and (iii) positioning the longitudinal axis of said filled containers between a mine roof and a mine floor oriented such that the top end of each container is distal from the mine floor and the bottom end of each container is distal from the mine roof.
