Abstract
A refined and improved self-sealing brattice for use in coal mine rescue and recovery operations for directing the flow of air was developed and tested. The brattice is made from a lightweight, low- cost material that meets Mine Safety and Health Administration flammability requirements. The units can be erected using pins, spads, or lightweight extensible poles. Tests were conducted to determine leakage rate from minimal to a maximum of 1.5 In h2o. The ability to handle reverse flows was demonstrated and a nonflammable foam was used as an auxiliary sealing agent.
