Innovative Solutions for Scanning Dangerous & Inaccessible Cavities in Underground Mining. GeoSight provides innovative solutions for scanning dangerous and inaccessible cavities in underground mining operations. Fast, real-time data acquisition decreases operator exposure time underground, reducing potential risk to the operator. Acquired data gives insight to stope production, helps extend site usable life, reduce dilution, calculate backfill volume, and investigate backfill and blast efficiency.
