Abstract
Case-study data from a series of three-dimensional scanning laser tests conducted at the Stillwater Mining Company's, Stillwater Mine in Nye, Montana, USA is presented. A series of blast rounds in two underground development drifts were scanned using a Leica HDS 3000 Scanning Laser. Detailed digital surveys from the scans were used to supplement basic blast audit data including location and orientation of drill holes, comparison of "as-designed" versus "as-built" and calculations of overbreak and underbreak. Operational considerations and feasibility of using the system as a research tool to quantify blast damage are discussed as well as the safety implications of improving blast designs.
