  • Patent number: 5308280
    Abstract: A hanger for a coal mine ventilation curtain has a support that is compressed against the mine surface, trapping the edge of a sheet of ventilation curtain material between a curtain supporting portion of the support and the mine surface. The support can be held in its compressed position against the mine surface by a tension member, such as a chain, that is attached to the mine surface (most readily at a roof plate) and is then secured to the support. Alternatively, the support can be held in place from the side of the support opposite the mine surface by a compression member (such as an adjustable support pole).
