The article discusses the use of terrestrial laser scanning to assess deformations in mining areas. Using the terrestrial laser scanning Riegl VZ-400, control measurements within the historical location of the underground coal mine in Zabrze were made. Two laser scanning measurements were taken over the course of one year. The research made it possible to determine changes in surface deformation on the shallowly located mining excavations. Differences in the terrain may be due to subsidence associated with the influence of underground mining and pose a threat to the adjacent road infrastructure and structures.

In the paper the problem of landslides in road engineering is discussed. An example is given of a landslide next to regional road No. 975 in Borowa. The analysed slope was modeled in the MIDAS GTS NX . The slope stability analysis and the FoS coefficient were carried out using the shear strength reduction method (SRM). In the next step a numerical analysis was carried out after the security measures were implemented. The results show the capability of numerical simulation programs.

In the article the problem of anthropogenic soils from thermal treatment of waste in terms of their use in road construction is discussed. As part of the research, the basic physical and mechanical properties of the anthropogenic soils were determined. PN-S-02205: 1998, the analyzed ground material (fly ash and slag mixture) qualifies as useful for embedding into the lower layers of the embankment below the freezing zone, provided they are in dry places or are insulated from water. The next step was to model an exemplary, unstable road embankment in the MIDAS GTS NX. The results point out that the strength and physical properties of the anthropogenic soils may be used to secure unstable road embankments with simple soil and water conditions. It should be remembered that analysed anthropogenic soils should also be subjected to rigorous testing for their chemical composition. The obtained results will allow us to determine the possibilities of their use in road construction in terms of their strength properties.
