(54) SUSPENDED, FASTENING FOR VERTICAL MINING OPERATIONS

The invention relates to the construction of mine workings and relates to the installation of suspended supports for the construction of vertical mine workings.

Known suspended roof bars for vertical workings, including a support ring, beams, fasteners, suspensions and puffs l ..:.

The disadvantage of this support is the complexity of its installation and demounting.

Closest to the invention is a lining, comprising a series of connected by suspenders rims of longitudinal and transverse beams with hubs 2j installed between them,

The disadvantages of this kretsi. the inconvenience of extracting the lining elements and the time spent on the installation and disassembly of the lining are, as the rims are wedged here using conventional wedges in a percussive manner.

The purpose of the invention is to remove rock pressure on the lining before dismantling it and to ensure ease of installation and de-assembly.

This goal is achieved by the fact that in the suspension support for vertical mine workings, which include a series of spliced crowns made of beams, with inlays installed between them, the beams are interconnected by means of eccentrics.

In Fig. 1 shows the lining, a general view; in fig. 2 shows section A-A in FIG. in fig. 3 shows a section BB in FIG. one; in fig. 4 is a section bb in FIG. 2;

10 in FIG. 5 is a section of YYD in FIG. 2.: The support includes a series of crowns, the number and distance between which is determined by the passport of the mine workings. On the surface, the treatment has a wellhead support 1.: Each of the rims is made in the form of, alternating around the perimeter of the suspended 12 and overhead 3 ba approx. Suspended beams 2 for connecting them with hangers 4 are provided with S-shaped fixed hooks 5, which, for convenience of hanging, and beams and hangers are facing the upper shed to the wall of the mine workings, and the bottom to its axis.

Beams 2 and 3 are integrally connected at the ends by means of an eccentric 6, which is fixed with the possibility of rotation in the suspension beam 2. For turning the eccentric by the crank,

30 holes 7. The total value of eccentricities of e-all eccentrics of the crown corresponds to an increase (at installation) or a decrease (at dismantling) of its perimeter. Between the crowns are installed the sleeves 8, for example, from boards, which, with their ends, enter the U-shaped grooves 9. In this case, the shelves of the 10 lower grooves facing the axis of the mine are made removable on rigid pins x 11 beams. The orifice support 1 for installation, hangers 4 and 8 is equipped with hooks with a U-shaped groove 13 along the entire perimeter. The lining assembly is performed in tajKoft sequence. Suspensions 4 are hung on hooks, wellhead support, and when assembling the subsequent crown - on hooks of the suspension beams of the previous crown. Suspension beams 2 hang on hooks 4 with hooks 5. The eccentrics 6 of the suspension beams 2 at the same time are eccentrically turned to the production axis, which corresponds to the smallest rim perimeter. On the eccentrics 6 of the suspended beams 2, overhead beams 3 are hung with their holes. The space between the assembled crown and the wall / wall of the excavation is laid with sawn waste and pieces of rock. Between the first one and the wellhead, 1, around the perimeter, are installed the knobs 8, while the upper ends of the knuckles are inserted into the u-shaped groove 13 of the wellhead, and when installing the next p and the second the crown, the lower ends are closed in the U-shaped groove of the beams of the wiring crown by means of the removal of the shelves 10, which are mounted with their holes on the rigid pins of 11 suspended and laid balances. By turning the eccentrics 6 to 180, the crown with the assembled pulls finally loosened in the excavation. The assembly of the subsequent crowns and the puffs is done in a similar order as the bottom of the mountain is pushed. I Disassembly of the fasteners is carried out in the reverse order, while turning the eccentrics on the 18СР to the initial position leads to a decrease in the perimeter of the crown and thereby ensures the removal of rock pressure on the disassembled vene1 | 1; and tightening and ease of installation and disassembly. Claims An overhead support for vertically mine workings, including rows of connected suspensions of rectangular rims of beams with fixings between them, is necessary so that, in order to facilitate the installation and disassembly of the support and the connection of mountain pressure from the lining before its dismantling, the beams are interconnected by means of eccentrics.
