Abstract

1471311 Mineral-mining installation GEWERKSCHAFT EISENHUTTE WESTFALIA 16 April 1974 [19 April 1973 16 June 1973] 16602/74 Heading E1F In a mineral-mining installation a mining machine guide 14 attached to one side of a conveyor 13 is adjustably tilted by means of an extensible thrust producer 44 which acts between the conveyor and a control bar 34 supported and guided on a movable roof support, the forward end of the control bar being articulated to the conveyor about a horizontal axis 49. Two parallel control bars are preferred and extend one on each side of a ram 36 used for advancing the roof support and conveyer. The thrust producer 44 is preferably an hydraulic ram, and various connections of the ram to the control bars 34 and the conveyer 13, are disclosed. A further ram (105), Fig. 5 (not shown), may be provided between the control bars 34 and the base member 21 of the roof support to adjust the height of the bars. The base member 21 may be provided with a pivotable forward extension (60), Fig. 3 (not shown).
