Reusable Support External to Strata

This section relates to such items as longwall chocks or breaker line supports. They are designed to allow some roof movement but to control major roof failure until after work at the location is completed. Details are included in the "Longwall" and "Pillar Extraction Using Continuous Miner" sections.
