Mineral raw materials for engineering works

Mineral raw materials for engineering works are usually clayey-sandy and clayey rocks, but also others - sandstones and limestones. These raw materials are utilized in road industry for road embankements building or in waste disposal packing and reclamation.

Usually (about 70 %) resources of mineral raw materials for engineering works are documented as accompanying raw material - these are the parts of deposits which do not meet the balancing criterias of the main raw material, i.e. parts of sand and gravel deposits with too high ash content or parts of dimension and crushed stones deposits with too low strenght.

Anticipated economic resources amounted to 7.79 million m3 in 2013 and decreased by 0.219 million m3 (2.7 %) in comparison with the previous year.

There was not any new deposit documented in 2013. There were new documentations approved for 3 deposits: Zalesie I (Mazowieckie Voivodeship), Rokitno I (Lubelskie Voivodeship) and Łazów-Galicja (Podkarpackie Voivodeship) due to the end of their exploitation. These deposits were crossed out of “The balance…”.

The table given below shows the current state of identification and management of mineral raw materials for engineering works resources in Poland.

Production of mineral raw materials for engineering works amounted to 117 thousand m3 in 2013 and decreased significantly in comparison with the previous year (by 78.4 %). The drop in production was due to lower demand for raw materials in road building sector.

The Podkarpcakie Voivodeship accounts for 70.3 % of total domestic production and Lubelskie Voivodeship accounts for 18.1 % of total production – it was the only Voivodeship with increasing production.
