(54) METHOD FOR REMOVAL OF WATER FROM COILS AND UNDERGROUND PRODUCTIONS

The invention relates to the drainage of pits for foundations of buildings and constructions, as well as underground workings, in particular to the removal of water with the inclusion of sludge.

A known method of cleaning the shaft water collectors, including the collection of water and sedimentation of sediment in the catchment basins, the stirring up of the remaining sediment, the collection of water with sediment and hydrotransport sediment 1.

The closest to k proposed is a method of removing water from underground workings, including collecting water and sedimentation, sedimentation by pumping water, drawing water with sediment and hydro-transporting sediment using a pressure pipe (2).

A disadvantage of the known methods is pumping water with sediment from it. passing directly through the soybean, which leads to accelerated wear of the pumping devices, which increase operating costs.

The purpose of the invention is to reduce operating costs.

Said aim dostngaets that sog- to pulley process comprising collecting water and precipitation of sludge in the catchment sump, it is suspended by pumping the water intake of water from the precipitate and the precipitate gidrotraisportirovanne via flowline sediment deposition is carried out at least two edge catchment otstoyjHliKax, and sedimentation of sedimentation is carried out by alternately pumping clarified water from a CH1DOG water collector through another one, moreover, hydrotransportation of the sediment from the purification. The water catchment basin is carried out under the pressure of water corresponding to its pressure in the pressure pipe.

The drawing shows a device for the removal of water from an underground mine.

15 two septic tanks, implementing the proposed} (enyy method.

The method is carried out in the following sequence.

Initially, the installation and directing of pumping water from one catchment tank to another is established, for this purpose it is made, for example, filled with mine water through channel I of the first catchment basin 2.

After filling it to the set level, the drainage pump 3 is prepared for start-up, for which the backpipe 4-6 of the discharge pipe 7 is opened, and the valves 8-10 are closed.

Then, the pump 3 is turned on, the clarified water from the first sedimentation tank 2 is sucked in via pipe 11 and further along section 12 of the pressure pipe 7 is injected into the second drain water collector 13, fills it and creates in it an overpressure needed to release mine water through the pressure pipe 7 to the surface.

The clarified water, dvnged along the bottom of the catchment basin 13 to the mine drainage pipe 7, washed it, carries sediment with it, and brings it to the surface.

After a certain time, the direction of pumping clarified water changes, the sedimentation tank 13 that is cleared of sediment serves to draw water, and the sump 2 is sealed and through it water is pumped to the surface.

Applying this method to remove water from pits and underground workings

will reduce operating costs by increasing the service life of the pump unit by 3-3.5 times.
