Abstract

1299216 Advancing mine roof support assembly BANYASZATI KUTATO INTEZET VARPALOTAI SZENBANYAK and ORSZAGOS BANYAGEPGYARTO VALLALAT 21 April 1970 [29 April 1969] 19096/70 Heading E1P An advancing mine roof support assembly comprises a series of props 6 each incorporating a shield unit 3, 5 having a base 1 and a cradle 16 slidably mounted thereon, a tiltable roof bar 11 provided with an adjustable cantilever extension and supports 25 for the cradle which supports are flexibly interconnected by part-spherical ends 29 of joint members received therein. Each support 25 rests on the floor of the mine, and is pivotably bolted to a guide bar 27. The cradle is provided with two projecting plates such as 20 each terminating in a guide rail, such as 21. The rails are arranged at different levels, the higher one preventing tipping of the coal-cutter and the lower one 21 acting to fix the container of a chain conveyor.
