    摘要: A slidable filling dam has along the heading dam segments (4) articulated in a hinged roof-bar (7) of a mine lining. The slidable dam has near-floor beams (1) which are provided at their ends with terminal eyes (2) to connect two neighboring dam segments (4) at the point of their connection with footings (9) by means of bolts (10, 11). The near-floor beam (1) has in its central part at least one central eye (5) to fix a hydraulic ram (6) pulling up segments (4) of the filling dam.
