Verifying the possibilities of using a 3D laser scanner in the mining underground

Abstract

Presented contribution introduces our current utilization knowledge of the pulse scanner Leica ScanStation C10 in situ mine workings. It is a device with a long-range laser beam that has excellent positional, length and angular accuracy and a very high speed laser scanning with a possibility of photographic documentation of scanned scene. The possibility of its use in mining conditions was tested in mine workings in closed polymetallic deposit of Zlaté Hory (Olomouc region, Czech Republic). Within realized surveying campaigns, the possibilities of using this technology were verified, especially for documentation of the current technical condition of the mines and their real spatial definition. Furthermore, it is possible to monitor and determine the spatial changes in mine features (movements and deformations). The analysis of the data based on the undertaken scanning campaigns and also with regard to the physical and technical constraints that were encountered, the technological procedures of each type of scanning were subsequently adjusted to the specific conditions.
