3D Laser surveying offers better judgment – Quarry

Jan 09, 2009  To precisely survey the rock face, it is imperative to determine the rock mass and the explosive energy needed to achieve objectives. Often geometrical errors occur in blast design because of incorrect face assessment and drill errors. FACE ASSESSMENT Poor face assessment errors can lead to poor yield, wasted explosive and prolonged drilling times.
