Shot Improvements through Field Controls: Applications of Passive Laser Survey Systems

The components of passive laser survey systems and their relative functions are presented. A general outline of the capabilities and the information available are followed by two case histories. These involve the use of such systems in quarry blasts where loading adjustments and drilling designs were required. Their application in blast casting operations, stockpile measurement, surface and underground construction, and general surveying areas are briefly covered, with comments on the potential for demonstrating a return on an investment in laser survey equipment.
