UNDERGROUND WATER COLLECTING RESERVOIR OF COAL STRIP MINE Russian patent published in 2017 - IPC E21F17/16 C02F1/00 B65G5/00 

FIELD: manufacturing technology.

SUBSTANCE: underground water collecting reservoir of a coal strip mine contains an impermeable layer and located downward from this layer a space for water storage and a cleaning layer. Space for water storage comprises first space for storage of water and second space for water storage. Cleaning layer comprises first and second cleaning layers. First cleaning layer is arranged horizontally in the space for water storage to divide it into the first space for water storage and the second space for water storage. First space for water storage is located below the impermeable layer and between the said layer and the first cleaning layer. Second space for water storage is located below the first space for water storage, and the bottom part of the second space for water storage is located in the lower part of the underground water collection reservoir of the coal strip mine. Second cleaning layer is arranged vertically inside the second space for water storage.

EFFECT: present invention due to building the underground water collection reservoir of the coal strip mine prevents useless water consumption in the process of coal production and due to availability of the cleaning layer in the underground water reservoir of the coal strip mine provides multiple water treatment, prevents environmental pollution and implements the water management policy during mining operations in the process of coal production.
