Abstract
838,192. Mine-roof supports. JANELID, E. I. July 11, 1958 [Feb. 25, 1958], No. 22338/58. Class 20(2) [Also in Group XXI] When a gallery is extended by drilling in to behind the gallery face from a parallel gallery 18 bores 3 for blasting charges which on being fired only blast down the face and leave a wall of rock between the galleries, the roof may be reinforced by drilling further bores 17 from the gallery 18 and inserting into these bores 17 rods or bars 16. The bars may be provided at the ends projecting into the gallery 18 with hooks by which the bars can be subsequently extracted from the bores 17.
