SAMPLING SYSTEM FOR CHECKING FOR IONS OF HEAVY METALS WHEN EMPTY COAL BED IS EMBEDDED IN MINED SPACE OF COAL MINES Russian patent published in 2020 - IPC G01N1/14 

FIELD: mining.

SUBSTANCE: invention relates to a system for sampling for inspection of heavy metal ions when empty coal bed is embedded in a mined space of coal mines. Disclosed is a system for sampling water for verification of heavy metal ions when empty carbon rock is embedded in a mined space of coal mines, comprising sampling devices and pipes for sampling, connected to the same number of sampling devices, said sampling devices are arranged in the worked-out space in rows through gaps based on the actual length of the face in the direction of the face advancement; rows of sampling devices are arranged at equal distance from each other; sampling devices are installed behind the support as the coal face advances; each sampling device is one sampling point; each sampling device is made in communication with one of said sampling pipes; said sampling pipes are arranged in the working face of the working face and are connected to the water pumps outside the worked-out area.

EFFECT: disclosed is a sampling system for checking for ions of heavy metals when empty carbon rock is embedded in the mined space of coal mines.
