Stones, sandpits and limestone quarries in the Czech Republic

Sand in this large sand quarry is mined from up to an 18 m thick wall, of which about 12 metres is under the water. The mining is carried out from below the water surface by a bucket excavator and subsequently by a suction dredge. The sand is then transported by tow boats for further processing. Due to the mining method, the sand quarry only produces washed sand with fractions of 0-4, 4-8, 8-16 mm. The sample for analysis was taken from the Cep II quarry, which is situated in a forest about 2.5 km north from Suchdol nad Lužnicí, west of road No. 24 (E49). The Cep and Cep I quarries, with only connected maintenance mining, are located near this quarry east of road No. 24.
