Abstract

1,150,679. Advancing mine roof supports. GEWERKSCHAFT EISENHUTTE WESTFALIA. 23 May, 1967 [4 June, 1966], No. 23896/67. Heading E1P. An advanceable mine roof support assembly comprises at least two parallel hydraulic roof support frames A, B, arranged prependicularly to a conveyor 19 and individually advanceable by a hydraulic cylinder 13 disposed between each pair of frames, or together, by two additional cylinders 21, 22 connecting the outermost frames to the conveyor 19 or a beam (not shown) parallel thereto. Each frame includes hydraulic props 11, 12, a roof bar (not shown) and a floor rail 10. The rail 10 of the frame A is connected by plates 18 and an elongated member 17 to the ends of a piston rod 15 extending through the ends of the cylinder 13 which in turn is connected by plates 16 to the rail 10 of the frame B. When the support assembly is advanced as a whole the frames may be locked together by a bar 29 inserted in a transverse bore in the piston rod 15.
