Mining exploitation has a negative impact on the natural environment. Voids created in the rockmass result in displacements and deformations of land surface. During planning and conducting the exploitation, the range of exploitation influence in the form of linear deformations is being determined. On the basis of mining-geological parameters of exploitation, the exploitation range of influences is calculated. According to the literature, many different ranges of exploitation influences can be determined depending on what has been the purpose of it. Different types of exploitation influence ranges can be distinguished, such as theoretical, damage or measurable. In the paper, the matters connected with determining those three types of the influence range are taken under consideration. The comparison of magnitudes of determined influence ranges is illustrated with two practical examples.Natural Hazards (2018) 94:979-997 https://doi.org/10.1007/s11069-018-3450-5( 0123456789().,-volV) (0123456789().,-volV)

The determination of landforms of the terrain depends on a number of procedures. In general, all these procedures can be subdivided into two groups. The first group consists of measurement activities related to obtaining real-life data. The second group comprises operations related to the processing of results, in order to obtain the imaging. The measurements of the terrain and its landforms are discrete. Cartographic images are continuous. In order to get a map of 3D measurements, contours need to be interpolated. In this publication, four of the many interpolation methods were selected for presentation: Global Polynomial, Inverse Distance, Radial Basis Function, and Kriging. The example of the measurement results for a syncline (a subsidence trough) is used in order to illustrate the comparison between the modes of operation of particular methods.
