Abstract
This article aims to present the possibility of using the low-cost iPhone 13 Pro LiDAR scanning device for inspections in the process of mineshaft sinking. The main goal of the research was to assess the accuracy and usefulness of the 3D models generated by the scanner. Measurements were performed at seven different concrete lining intervals before the final lining was completed. The measurements were made at the GG-1 ventilation shaft in Kwielice, Poland, at depths from 1320 to 1350 m below ground level. For better understanding of the true potential of using simple spatial models in the shaft sinking process, part of the shaft sinking cycle, in accordance with PeBeKa working technology, is first presented. Validation using professional TLS demonstrates the usefulness of the iPhone 13 Pro LiDAR scanner for the purpose of inspections that do not require a high level of accuracy. Additionally, a quick and reliable method of volume calculation using open-source software is shown and evaluated.
