Abstract

The invention relates to the mining industry and makes it possible to increase safety and ensure deserted cleaning of mine sump from solid impurities simultaneously and simultaneously with pumping out mine and canal water without stopping the main type of work carried out in shafts. Dp this bottom of the receiving tank is made in the form of reinforced concrete floors in the form of an inverted truncated cone, and the hydrotransport means is made in the form of a bunker-chamber 1 of a hydraulic feeder. The overlap is fixed in the shaft of the shaft and forms with the latter a vertical water collector 13. The bunker-chamber 1 is located in the body of the overlap coaxially with the shaft of the shaft or away from the axis. Solids under their own weight are bypassed into the bunker-chamber 1 with the valve 3 closed and the valve 2 open. Then the pressure in the bunker chamber 1 and the conduit 5 is equalized, the valve 3 is opened, and the valve 2 is closed. When operating pumps 7 or 8, pulp is formed in the mixing chamber 4, which is fed to a drain through slurry line 6. 1 sludge. (L

The invention relates to the mining industry, in particular to the cleaning of mine shafts in the development of minerals, including deep and ultra-deep coal mines and processing plants,

The purpose of the invention is to increase safety and ensure deserted cleaning of mine sump from solid impurities at the same time and simultaneously with pumping out the mine and barrel water inflows without stopping the main type of work carried out in the shafts.

The drawing shows a diagram of a device for cleaning mine sumps (inclined walker for emergency exit and ventilation not shown).

A device for cleaning pedal sumps consists of a bunker-chamber 1 of a hydraulic feeder with a loading and discharge mouths with valves 2 and 3 installed in its mouths. A conduit 5 is connected to the throat with the valve 3 and the mixing chamber 4 on one side for discharging the solid slurry component, and on the other for the pulp channel 6 for delivering the pulp to the discharge point. The conduit 5 is connected to the transport pump 7 installed in the main drainage system or with the recessed 8 and suction .9 mechanisms. The additional emergency sump pump 10 is hydraulically coupled to the suction mechanism 9 k to prevent water from flooding the ventilation walker II and machine chamber 12, it can also feed the emergency pulp directly into the common water collector.

The bunker-chamber 1 of the hydraulic feeder is installed in a reinforced concrete floor, having the shape of an inverted truncated cone or wedge, and is placed with the shaft of the shaft under the sump vertical sump 13 or aside, not beyond its perimeter. To make it easier for the paddle to slide into the neck with the valve 2 bottom. The receiver has a funnel-shaped shape in the form of an inclined bottom 1Ao. To access gate 2 in the reinforced concrete body, there is an overlap of the cavity containing the pipeline 15c with the valve, ending inside the bunker chamber with a perforated pipe 16, designed to layer-by-layer scour material and equalize pressure in the chamber with pressure in the conduit 5.

To save energy, hydraulic slurry from deep and ultra-deep sumps of the order of 130 m has conduit 5 with slurry leads 6, as well as conduits 17 and 18 operate in a hydraulically balanced U-shaped pattern.

A device for cleaning mine sump works as follows.

For deep and ultradeep mines, a hydraulic feeder-shaped vehicle 1 is placed in the body of a reinforced concrete slab coaxially with the barrel or away from the shaft axis to transfer intracameral pressure to the pillars. Reinforced concrete wedge-shaped overlap is both lining and for sump and shaft providing safety of people in case of breakage of ropes, etc., which may be located in machine chamber 12. Solids under their own weight are passed into the bunker chamber I of the hydraulic pit ate with the gate valve 3 closed and open 2. Thereafter equalize the pressure valve 3 is opened and the valve 2 is closed and the pump running, 7 or 8 in the mixing chamber 4, the pulp is formed, which is supplied to the discharge point

With the valve 3 closed and the hydraulic mixture 2 opened, the water from the receiving tank is transferred by gravity into the bunker chamber 1, the water is displaced until the chamber is filled to a predetermined level.
