Description

.

The invention relates to mining and can be used for mine development workings.

The purpose of the invention is to increase the rate of penetration of production by reducing the labor intensity of the support installation in the bottomhole.

Figure 1 - development, longitudinal section; figure 2 is the same, the view in the plan; on fig.Z - the same, cross section; figure 4 - lining, General view; figure 5 is the same, side view; Figure 6 shows a stopper with an isometric bracket; 7 - lining folded; in Fig. 8, the node I in Fig. 4 shows the articulation of the upper with the stand.

Frame lining contains lining equipment, consisting of combine A, containing chassis 1, frame 2, working body 3, loading plate 4, conveyor 5, mounting table 6 with a guide for assembling frame lining and transferring it to working body 3 , a device 7 for raising frame support, located on the boom 3 of combine A.

Frame support B consists of a top 8, side posts 9 and 10, which are made at the junction with the top curved, flexibility nodes 11, spring taps 12, the ends of which are interconnected by sheet material 13 fixed on the top 8, by clamps 14. Ramna lining B in the collection laid on the mounting table 6.

Frame support B is mounted in excavation 15 at the pile of the bottom 16. Also shown are ventilation pipe 17, a conveyor for transporting black coal 18.

The support is installed as follows.

The parts of the support B in the form of the top 8, racks 9 and 10 with the lock 11 and the pins 12 are fed to the combine A on the assembly table 6. On the assembly table 6 the support is mounted

integrated, stacked and stacked on it. The assembled bracket remains on the assembly table until the next gate is passed by the combine. As soon as the entry is completed, combine A stops. The support B feeds from the device 7, located on the boom 3, and with the help of the arrow is installed in the excavation. The support is extended and extended using hand-held jacks (not shown).

Depending on the geological conditions, the entry can be completed on one or three lining frames. After installation, the support work cycle is repeated.
