Conventional stoppings of concrete block or wood walls covered with mortar-type sealants, urethane foams, or heavy brattice cloth work well in many mining applications, but the time and cost of constructing and maintaining them can make them impractical, especially when only temporary stoppings are needed. They do not lend themselves to use at or near the working faces of mines where heavy blasting is done because of the damage they incur. Thispaper describes the parachute stopping, quick-fix blowout stopping, and damage-resistant brattice, recently developed by the Bureau of Mines, that are much more suitable for such applications.
