Mining

3D documentation using laser scanners is a swift and reliable method of assessing resource depletion in open-cast mining facilities (open-cast mines, quarries, sand and gravel pits, spoil heaps etc.) and of making accurate calculations of volume and mass.

The same methods can be used to survey subterranean mines and other complex cavities (galleries, caves, wells, cellars etc.). The laser scan surveys are quickly accomplished requiring only a few stationings of the equipment. The survey values are then processed and data is extracted concerning the edges of slopes and mined areas. We can also generate digital terrain models (DTM), contour line maps and complex 3D cavity models during data processing.

Example: Historical Mining Gallery at Bartholomaeberg, Austria Task: Topographical recording and survey of subterranean mining galleries Area: Approx. 2.5 hectares Data acquisition: Laser scanner and total station surveys Data quantity: Approx. 42 million points Result: 3D model Animations: Flash (approx. 1.5 MB)   RealVideo, Modem/ISDN*   RealVideo, Broad Band*   * To view this video you need the RealPlayer software.
