Abstract

1,079,706. Self-advancing pit-props. STAMICARBON N.V. Nov. 30, 1964 [Dec. 2, 1963], No. 48631/64. Heading E1E. A mine roof support comprises a pair of prop units, connected above floor level, with runners 18, 19, 18', 19' engaging spaced parallel rails 6, 7, 6' , 7' on a central structure 5. One arm 16 joining runners 18, 19 passes over a piston-and-cylinder-unit 8, 10 mounted on the roof support and the other arm 16' passes under it. In a modification there are three guide rails on the structure 5, a runner of each unit engaging an outer rail and part of the middle one, which is lower than the other rails, and unit 8, 10 being mounted between them and above the middle rail.
