Seeing through the shotcrete – enhancing geological modelling with FaceCapture Mapping at Renison
The Renison Mine, situated on Tasmania’s West Coast, is owned and operated by Bluestone Mines Tasmania Joint Venture Pty Ltd. Operating as Australia’s largest primary tin producer the deposit was initially discovered in 1890, with modern underground production beginning in the late 1960s and continuing to present day. The mine reaches a depth greater than 1200 m below surface and currently has a projected mine life of 10 years. The Renison Mine is geologically complex and, at depth, ground conditions have become more dynamic. This has necessitated the installation of dynamic ground support that includes frequent shotcreting of headings to mitigate seismic risks, resulting in more variable and narrower windows for collecting geological data such as backs mapping, structural information and heading photos. Mine Vision Systems (MVS) FaceCapture Mapping (FC Mapping) was recently introduced into the underground mine geology workflow as a means of collecting geological information through a high-resolution 3D georeferenced laser scan in this increasingly time constrained environment. FC Mapping combines LiDAR scanning with high resolution photography. This is the first use of MVS technology in Australia, and to date FC Mapping is proving valuable with scans being efficiently integrated into existing geological modelling processes. The MVS system is a portable unit with all scan processing performed within the unit in real time. Resultant file sizes are small, adding to the flexibility of integration to Leapfrog and Surpac. The introduction of the FC Mapping has not come without challenges. Strategic considerations include, underground conditions, integration into the underground operational workflow, reference point error, and understanding the quality of scans required for geological modelling versus geological backs mapping. This paper provides a summary of Renison Mine’s integration of the FC Mapping, how this process has contributed to our geological decision-making, the challenges encountered, improvement opportunities, and future works envisioned.
