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.
