(54) UNDERGROUND PUMP INSTALLATION OF MINE

WATERFLOW

This invention relates to the field H) p. it does business, namely to mine drainage.

A known device for the drainage of preparatory mine workings includes a drive filter, an aeration well, a piping system, and a drainage groove ij.

A disadvantage of the known device is that underground waters from overlying aquifers are passed into the drainage grooves of the underlying underground mining workings, not using this weight of stump of underground waters poured from the stands.

Also known is underground underground installation of mine drainage for pumping out groundwater from mine workings, including from outcropping horizons, to the surface,

including pumps and electric drives installed in the pump chamber, passed on the underlying horizon, a system of suction, discharge piping, shut-off valves mounted in the mine workings, and means allowing free discharge of groundwater from the overlying horizons and underlying 2.

The disadvantage of this pumping unit is that it does not utilize: the tensile energy accumulated in the overlying waters of the horizons, since the waters of them are freely drained into the grooves of the mine workings, preceding the underlying horizons.

In addition, it is required to expend additional electricity to restore the level of groundwater when pumping to the surface.

The purpose of the present invention is to increase the efficiency of mine drainage.

For this, the means for transferring groundwater from overlying horizons to the lower horizons are connected to pipelines of an underground pumping installation into a single system of communicating vessels.

The underground pumping station for mine drainage includes the drainage grooves 1 of the mine workings of the upper horizon and aquifer 2, the drainage grooves 3 of the underlying horizon, the water collector 4, the pumping chamber 5, the pipeline system b and 7, the pumps 8 and groundwater mirrors 9 and 10..

Groundwater from the drainage grooves 1 of the mine workings of the upper horizon and aquifer 2 is not overflowed into the drainage grooves 3 and the water collector 4 of the pumping chamber 5 of the underlying horizon but enclosed in the pipeline system 6 connected to the pipelines 7 of the subsurface pumping unit. When the vasos 8 of the pumping installation on the lower horizon does not work, the pipelines 6 and 7 will naturally be flooded with groundwater to the level of the water 9 of the aquifer 2. When the pumps 8 start to work, they are draining at the underground design. Pschzemny waters are sucked into it from two marks at once - from the water level mark Yu, which is in the catchment 4, and from the mark of the beneath waters 9 that fell into the associated water supply 7 and 6.

With this device of an underground drainage installation, the water level in the pipes will always be at the bottom of the mirror overflowed to the lower levels of the water. In this case, the rise of water in the drainage pipelines to the level of the groundwater table is due to the energy of the weight of the water column found in the nepenycKaf Mbrx pipelines. Consequently, it is no longer necessary to waste energy on raising the groundwater to this level.

This invention makes it possible to use the energy of a weight of a groundwater column located in pipelines between the water markers to raise the recorded amount, groundwater to the water pressure level or to start the drainage groove of the overlying horizon, thereby increasing the efficiency of the underground pumping installation of the shaft mine.
