Terrestrial Laser Scanning and Global Navigation Satellite System technologies are increasingly prevalent in geodetic mapping work, playing a significant role in mine surveying tasks such as drawing maps for volume calculation, monitoring displacement, and deformation of mine surfaces and structures above mine tunnels. Currently, there are many studies on the application of these technologies in various aspects of mine surveying work. This paper will synthesize these studies to evaluate the effectiveness of applying GNSS and TLS technologies in mining surveying. The authors has reviewed 44 papers/projects in recent years and found that these technologies are developing rapidly, with the accuracy of coordinate and altitude measurement increasingly improving to approximately millimeters in both horizontal and vertical directions.

Technologie naziemnego skanowania laserowego (TLS) i globalnego systemu nawigacji satelitarnej (GNSS) są coraz bardziej powszechne w pracach związanych z kartowaniem geodezyjnym, odgrywając znaczącą rolę w zadaniach geodezyjnych w kopalniach, takich jak two-rzenie map do obliczania objętości, monitorowanie przemieszczeń i deformacji powierzchni i konstrukcji nad wyrobiskami górniczymi. Obecnie prowadzonych jest wiele badań nad zastosowaniem tych technologii w różnych aspektach prac geodezyjnych w kopalniach. W artykule dokonana została synteza tych badań w celu oceny efektywności zastosowania technologii GNSS i TLS w górnictwie. Autorzy dokonali przeglądu 44 artykułów/projektów z ostatnich lat i stwierdzają, że technologie te bardzo szybko się rozwijają, a dokładność pomiaru współrzędnych i wysokości wzrasta do poziomu pojedynczych milimetrów zarówno w kierunku poziomym, jak i pionowym.

Wind turbines are among the key equipment needed for eco-friendly generation of electricity. Maintaining wind turbines in excellent technical condition is extremely important not only for safety but also for efficient operation. Studies indicate that defects in the external structure of a turbine blade reduce energy production efficiency. This research investigated the potential of the terrestrial laser scanning technology to examine the technical conditions of wind turbine blades. The main aim of the study was to examine whether terrestrial laser scanning measurements can be valuable for wind turbine blade condition surveying. The investigation was based on the radiometric analyses of point clouds, which forms the novelty of the present study. Condition monitoring focuses on the detection of defects, such as cracks, cavities, or signs of erosion. Moreover, this study consisted of two stages. The next objective entailed the development and examination of two different measurement methods. It was then identified which method is more advantageous by analysing their effectiveness and other economic considerations.

Spatial data obtained by Terrestrial Laser Scanning (TLS) can be used in order to create various inventories and analyses of the surveyed surfaces. This paper presents a use of orthogonal regression line in order to identify the beam's incidence angle on the surveyed surface as well as identification of roughness parameters using data obtained by terrestrial laser scanning. Accuracy of the visualisation of the surface and roughness parameters, in particular Ra (mean arithmetic deviation of surface roughness profile forming the average line) are closely correlated to the scan resolution of the evaluated area. Presented analyses indicate a need to identify areas with uniform visualisation [1,2] in the compared scans.
