Scanning total stations in solving mine surveying tasks in underground mining of the Perevalnoye deposit

The article presents a comparative study of two laser scanners, i.e. GO SLAM and Void Scanner VS+, for solving mine surveying tasks at the Perevalnoye field in underground mining. The focus is made on analyzing the operation of devices in difficult conditions of the underground environment, such as dust, gas contamination and high humidity, during the laying of rubble concrete. The purpose of the study was to conduct a comparative analysis of the technical characteristics and performance of the scanners in practice. The research methods included analysis of the geological structure of the site, selection of a stope for experiments, studying the technical characteristics of the scanners, a methodology for comparative measurements in dusty and dust-free conditions, analyzing the influence of external factors of the underground environment and assessing the cost and availability of the equipment. The results of the study indicate the advantages and limitations of each scanner in different conditions. GO SLAM showed high resistance to adverse conditions and efficiency in rapid scanning, while Void Scanner VS+ provided high measurement accuracy under favorable conditions, but had limitations in a polluted environment.
