Modern resources management with terrestrial lasercanning (TLS)

The application of structural 3D modelling using TLS datasets improves the extraction management and allows operating companies to differentiate distinct parts of a mineral deposit to be extracted with respect to different products.

1 Introduction

Operating mining companies need to face today’s market challenges in both economic and ecologic ways. The cost-effective production combined with a sustainable extraction management in active and future mining can be supported by the combination of the methods presented in this article. Terrestrial Laserscanning (TLS) is based on the LiDAR method (Light Detection and Ranging) and is used (1) to display the morphology, (2) to get information about layer orientations, and (3) to discriminate rock types and hence, raw material classes. Then, 3D modelling is used to combine the data...
