Abstract

1,069,905. Mine roof supports. K. M. GROETSCHEL. May 14, 1964 [Aug. 29, 1963], No. 20053/64. Heading E1E. In a mine roof support comprising a roof superstructure mounted by props on a base, the superstructure carries on the rear or goaf side an extension comprising one or more forepoling arms pivotably movable relative to the superstructure as by an hydraulic ram 27 acting on wedges 26. For modifications of the superstructure and other details Figs. 3-9, (not shown).
