Abstract

1,213,024. Mine roof supports. MICHELIN & CIE (COMPAGNE GENERALE DES ETABS. MICHELIN). 28 Feb., 1968 [3 March, 1967], No. 9718/68. Heading E1E. A mine roof support comprises on inflatable cushion 1 surmounted by a resilient mattress 4 consisting of a bolster of elastic, cellular material 4A covered by an elastomeric sheet 5. The sheet 5 may have grooves, slits or ribs to increase its flexibility and be reinforced by flexible filaments or cables for fuller details of which the Specification and Figs. 2..5 (not shown) should be referred to.
