Description

one

The invention relates to the mining industry and can be used in the development of mineral deposits by the underground method with the laying of the goaf.

The purpose of the invention is to intensify the process of laying and increase the quality of the formed bottom of the chamber.

FIG. 1 shows the layout of the camera being laid; in fig. 2 is a section A-A in FIG.

In transport openings 1, temporary filling pipes 2 are laid, which have taps 3 with valves 4. Taps are installed behind insulating bridges 5-12 in their upper part. At one of the bridges 5, which is closest to the zone into which the backfill mixture from the main filling pipeline 13 enters, on the side opposite to the isolated depleted space, install a pump 14, and suction pipe 15 is set up for moving into the backfill mixture 16. Pressurized A pump nozzle 14 is connected to the route of the temporary filling pipe.

The bookmark is as follows.

After preparing the bottom of the chamber for a bookmark, the filling mixture begins to flow into the chamber from the filling pipe 13. Mixture 16 enters the zone at jumper 5. After accumulation, the amount of the mixture is necessary to ensure

the liver of the normal operation of pump 14, with its help, the mixture is forcibly supplied for jumper 6. At the same time, all valves in the branches are closed, and

5, only the valves on the line (bottom in Fig. 2) are opened and on the branch at jumper 5. After filling up the developed space behind jumper 6 to a level equal to 1.5 m from the bottom of the jumper, open the valves, allowing the mixture to flow through the jumper 7, and the valve on the branch at jumper 6 is closed. Then, in a logical way, one fills the space to a height of 1.5 m behind the remaining bridges 8 (9.10 ...). By the time of filling the space behind the jumper 12, the mixture is laid

20 for the jumper 5, hardens, and it is possible to carry out the laying of the next layer in the bottom of the chamber to a height of 1.5-2 m above the previously laid layer. This is done in the same way as

25 described above. If necessary, during the third cycle, the above-equipped space can be completely laid down to the upper level of the jumpers. After laying out

30 spaces behind the last jumper 12, the pump 14 and the temporary piping 2 are dismantled, the jumper 5 is raised to the design height and continue to fill the chamber’s developed space
