Stones, sandpits and limestone quarries in the Czech Republic

The extensive sand quarry (covering an area of about 360 ha) is located about 1.5 km northeast from the village of Dobřín, near the train track leading from Roudnice nad Labem to Kralupy nad Labem. Sand is mined by floating bucket excavators from below the water surface of two bodies of water – the Dobřínské and Račické lakes. The total wall height is up to 16 m, out of which 10 metres are above the water surface. The mined materials are transported from the quarry using belt conveyors to the treatment plant, where it is washed and sorted. The treatment plant is equipped with a grinder for the oversized parts. The quarry produces washed sand with fractions of 0-2, 0-4 and 0-8 mm.
