Abstract

1418075 Advancing mine roof supports CHARBONNAGES DE FRANCE 26 Feb 1973 [28 Feb 1972] 9400/73 Heading E1P In an advancing mine roof support system for a longwall face incorporating supports of lift and "walk" construction each roof beam 1 is connected to a continuous supporting shaft 11 extending along the face by means of a sliding coupling disposed inside the said beam. The bottom of the beam forms a slide 5 slidably received in stirrups 6, 7 which are interconnected by a bar 8 and have elongated holes 10 to receive shafts 11, 12. A continuous shield 23 is provided on the goaf side connected to lifting jacks 24; bracing jacks and bracing rods 17, 18 also being provided, as shown. In a modification, see Fig. 3 (not shown), each support is provided with an adjustable front shield to support the coal face and the system is provided with a shield in the form of a curtain fixed to an articulated frame.
