  • SKIN FAILURE OF ROOF AND RIB AND SUPPORT TECHNIQUES

    SKIN FAILURE OF ROOF AND RIB AND SUPPORT TECHNIQUES IN UNDERGROUND COAL MINES By Eric R. Bauer1 and Dennis R. Dolinar1 For instance, in 1997 more than 800 miners were injured by roof and rib falls, of which 98% were the result of skin failures [Bauer et al. 1999]. Also, nearly 80% of the roof control, and machine design modifications
