Description

pi / z.f

The invention relates to the mining industry and can be used in the underground mining of mineral deposits with hydraulic laying of the worked-out space on gentle formations with unpatched thickness and complex hypsometry.

The aim of the invention is to improve the filling of the worked-out space with a hydraulic bookmark when working on flat seams with poor power and complex hypsometry.

Fig. 1 shows a schematic of the device for hydraulic bookmarking during the backfilling process, side view; Fig 2 is the same, top view; FIG. 3 is a section, A-A in FIG. 1,

The main pipeline 1 is laid in the mine workings adjacent to the above-labeled space to be laid. The main pipelines 4 and 5 located opposite the worked-out area are connected to the main pipeline through the valves 2 and .3. Flexible collapsible backfill pipe 6 is connected by one condom to outlet 4 and through; clamps 7 with rollers 8 are movably suspended on the monorail 9 fixed at the roof of the developed space and the route of which repeats the longitudinal profile of the roof of the developed space.

The free end of the backfill pipe 6 is a release of the inlet

placed below the monorail 9, Before the cuff 13, in the direction of the outlet of the backfill pipe 6, a sensor 15 is installed to monitor the filling of the developed space. Mobile compressor 16 and receiver 17 are connected via compressed air line 18 and valve 19 to outlet 4 of main pipeline 1, and through valve 20 to outlet 5,

The device works as follows.

The stowing material from the main pipeline 1 through the valve 2., the outlet 4 is fed into the stowing pipe 6, from which it enters the worked-out space, and fills a part of its volume bounded by the spreading surface of the stowing Material corresponding to the limiting spreading angle. The sensor 15 for monitoring the filling of the open space is turned on, the valves 3, 19 and 20 are closed.

During the filing of the filling material through the filling pipeline 6 into the developed space, the compressor 16 provides for filling the receiver 17 with compressed air.

When the sensor 15 is turned on, the valves 3 and 19 open, the valve 2 closes. In this case, the backfill material from the main pipeline 1 enters the outlet 5, and the marginal air coming from the receiver 17 through the pipeline 18 displaces the remaining in the outlet 4 and the backfill pipe 6. backfill material in the developed

additional material into the developed space. Then the valve 19 is installed, to the clamps 7 there are attached cables 10, which through guide blocks 11 are connected to the drum of the winch 12, the section cover is fixed on the roof of the worked out space and is located around the monorail 9, the backfill pipe 6 and the cables 10 on portions of the backfill pipeline route 6 with a positive tilt angle in the vertical plane that exceeds the spreading angle of the backfill material.

The cuff 13 is made of elastic material and is located around the backfill pipe 6 on the discharging part thereof. The cross-sectional area of the cuff 13 corresponds to the cross-sectional area of the casing 14, disconnected, and the backfill pipe 6 is disconnected from the outlet 4 and the backfill pipeline is shortened by one link. , the roller 8 on the monorail 9 is pulled to the outlet 4, if the sensor 15 is turned off, then the backfill pipe 6 is connected to the outlet 4. If the sensor 15 remains on, then the next link of the backfill pipe 6 is disconnected to off Cheney sensor 15.

When the discharge casing of the backfill pipe 6 is located in the casing 14, the sensor 15 remains on. After connecting the backfill pipe 6 to the outlet 4 turn on

engines 2 and 20, and the valve 3 is turned off. In this case, the filling material from the main pipeline 1 enters the outlet 4, and the compressed water displaces the filling material left in the outlet 5 into the hollow space. Then the valve 20 is turned off. The above actions are repeated until the above-filled space is filled with filling material for its entire length.

The device provides a reduction in the cost of backfilling and increase productivity.

Formula of the invention
