A four-prop mine roof support comprises two U-section floor beams 3 each having a superstructure 4 carrying rubber-lined clamps 9 resiliently supporting two hydraulic props 6 carrying a roof beam 14, the two structures 4 being interconnected by mutually-perpendicular plates 23, 24 which can twist to accommodate floor irregularities. The vertical plate 23 has flanged edges and is secured to upstanding rear plates of the structures 4 by bolts and spacers; the horizontal plate 24 is secured to the structures 4 by individual bolts 28 and is coupled by a bolt 29 to a lug on the plate 23. Each prop 6 stands in a socket on its floor beam 3 and has at its upper end a socket pivotally receiving a spigot on .the underside of the roof beam. As shown the floor and roof beams 3, 14 are hinged to extension beams 17, 21 coupled by props 19. The whole support may be connected by an advancing jack to a conveyor or other anchorage.
