Mineral raw materials for engineering works

General information

To the group of mineral raw materials for engineering works there have been deposits often called as “earth masses for building purposes” classified. They are usually clastic rocks of a clayey-sandy characteristic e.g.: silty sands, loamy-clayey sediments and mantle rocks, and solid rocks: sandstones, limestones, conglomerates, allocated from the deposits as not fulfilling the criteria necessary for the crushed aggregates production. These raw materials are utilized in the road industry for the road embankments building and the maintenance of dirt roads surfaces. The loamy-clayey raw material can be used for the packing and reclamation of waste disposals, for hydro-building and other purposes. The usefulness of these raw materials is determined by i.e. their geological-engineering parameters, sealing (isolating) properties and others. Usually, the mineral raw materials for engineering works are documented as an accompanying raw material in sand deposits or deposits of the solid rock materials, covering their worse, defective parts. Only in about 30% of cases are documented as the main raw material.

Resources and output

The total anticipated economic resources amount to 11.768 million m3. In comparison with 2018 they increased by 0.433 million m3 (it means by 3.8%).

In 2019, there was only 1 new deposit documented: Szaniec in Świętokrzyskie Voivodeship, with the total resources equal 0.733 million m3 of sands for the road embankments building. Any other geological elaboration was recorded in 2019.

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

The output of mineral raw materials for engineering works amounted to 0.296 million m3 in 2019 decreasing by 0.034 million3 (10.3%) in comparison with the previous year. There were 11 deposits under exploitation.

The economic resources were calculated for 12 deposits. They amount to 4.804 million m3 in total which accounts for 85.4% of the anticipated economic and the sub-economic resources of these deposits.

The figure given below shows changes in domestic resources and production of mineral raw materials for engineering works in Poland in the years 2000-2019.
