PUMPED-STORAGE PLANT Russian patent published in 2007 - IPC E02B9/00 

FIELD: hydroenergetics, particularly water-power plants, namely pumped-storage plants, which generate power in on-peak period.

SUBSTANCE: pumped-storage station comprises upper and lower accumulation pools connected with each other by means of pressure waterway, hydroelectric generators and supplementary equipment. Upper accumulation pool is arranged in completed breakage heading of upper horizon adjoining shaft or in waste dump formed on ground surface during deposit development. Lower accumulation pool is located in completed breakage heading of lower horizon adjoining the shaft. Each accumulation pool located in completed breakage heading is made as breakage headings communicated with each other through cross headings passing through barrier pillars in upper and lower parts thereof. The breakage headings are separated from active mines with water-tight partitions and connected with atmosphere through inclined cross-headings extending from the shaft. Hydroelectric generators are installed in headings made at shaft bottom in lower horizon. Pressure waterway is arranged in shaft.

EFFECT: decreased costs for pumped-storage plant erection.
