Abstract
This invention is directed to a means for transporting a mine roof support set including a plurality of nested containers. Each container in the set has a progressively smaller cross-sectional dimension, or a tapered, frusto-conical shape, to allow the containers to be nested one within the other. The plurality of nested containers allows more efficient 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 then placed with their longitudinal axis between a mine roof and a mine floor.
