Abstract

An adjustable goaf shield 1 acting as a backfill screen is mounted on hydraulic rams 7 and is hinged to the base 5 of a support frame at 6 so as to be pivotable about a horizontal axis. The shield 1 comprises two overlapping screens 2, 3 connected to opposite ends of the rams 7, and its angle is adjustable by rams 8 mounted on rear props 4. The top of the screen 3 is fitted with a sealing element 9 having an internal stiffening web 10 made of flexible material. <IMAGE>
