Abstract

In recent years, the growing interest in new techniques for spatial data acquisition, processing and analysis has also found applications in surveying and geological departments, where it is used in the process of developing documentation. In the conditions of mining operations, surveying measurements must be carried out quickly, safely and with sufficient accuracy. The use of laser scanning allows the collection of a significant amount of data, which requires time-consuming processing, but is necessary for accurate modelling of objects in 3D. The legal basis for the use of laser scanning in mining is the acts that regulate activities in the field of surveying, geological survey documentation and technical standards for surveying. The process of implementing laser scanning in underground mining requires compliance with occupational safety regulations and technical standards, as well as proper training of personnel. The laser scanners used in practice are equipped with the SLAM algorithm, enabling precise measurement and point cloud generation. Appropriate software is crucial for processing and analysing the collected data. The use of laser scanning makes it possible to efficiently perform non-standard measurements, which contributes to streamlining work at mining facilities. However, to realize its full potential, it is necessary to train personnel and raise the level of use of this technology.
