• Description:
  The Bureau of Mines has developed a damage-resistant brattice, intended for use as a stopping in locations where blast damage to stoppings is a problem, the roof is relatively flat, and the differential pressure across the stopping is not high. Damage- resistant brattices consist of a series of vertically hung brattice panels joined to each other by velcro connections that improve the airtightness of the brattice. When the brattice is subjected to strong blast forces, the velcro connections peel apart, allowing the panels to open without incurring damage. The velcro connections can then be resealed in a matter of minutes. A preliminary test in the Bureau's safety research mine and subsequent long-term testing at the White Pine Copper Mine in Michigan and the retsof salt mine in New York show that damage-resistant brattices withstand blasting better than conventional stoppings, while still performing as efficient air barriers when the velcro connections are sealed.
