  • Generator for dynamic loading of a mine lining
    Patent number: 4718793
    Abstract: A generator for dynamic loading of a mine lining simulates an unstable ground structure, such as a "bump" of the formation roof by an explosion of an explosive. The generator /3/ comprises a cylinder /6/ with a piston /7/, the said piston functioning as a percussion member. The bottom of the cylinder /6/ is provided with symmetrical chambers /10/ to place an explosive. The explosive is batched to each of chambers /10/ through holes /8, 9/ made in the flank of the cylinder /6/. Holes /8, 9/ are bored at an angle enabling gravitational filling of the chamber /10/ with an explosive already after initial spragging of the lining section /1/ under test between the floor /2/ and the generator /3/ abutting the roof /5/ of the test-stand. The cylinder /6/ is closed with a limiter /12/ of the stroke of the piston. Between the piston /7/ and the limiter /12/ of its stroke there is a shock-absorbing washer /13/. In the limiter /12/ there are additional holes for release of powder gases.

  • Slidable filling dam
    Patent number: 4406565
    Abstract: 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.

  • Nine lining structure
    Patent number: 4382722
    Abstract: The roof support according to the invention is between the roof-bar (2) and the sill piece (1) with at least one system of levers (3,4) connected by articulation with each other and connected by articulation with the roof-bar (2) and the sill piece (1) so that they have the form of a lying letter V directed with its vertex towards the fall. Between the levers (3,4) it is provided with the hydraulic cylinder (5) spragging the levers (3,4) and thus the lining. That admits to achieve a high multiplication of the cylinder travel in relation to the change of the lining height, and a multiplication of forces. In shield roof supports of a lemniscate type the lever system can consist of the fall shield (6) and the outside arm (7) of the lemniscate arrangement.
