Self-Sealing Brattice for Coal Mine Rescue and Recovery.

PB258077

Publication Date	1976
Personal Author	Kissell, F. N.; Thimons, E. D.
Page Count	11
Abstract	A self-sealing brattice intended for use during coal mine rescue and recovery operations has been designed and tested by the Bureau of Mines. The major design difference between self-sealing and conventional brattice is that the fabric is cut and sewn as a hemisphere instead of as a flat sheet. This new type of brattice offers reduced weight, leakage, and installation time. Preliminary testing indicates that the concept is worthwhile, but that further developmental research is required.
