The Use of Terrestrial Laser Scanning (LiDAR) for the Analysis of Blasting Results

Abstract

An important efficiency criterion of the blasting operations in mine production is the degree of fragmentation. Different methods have been used to determine the fragmentation up to the present, however some difficulties such as measurement error and long operation times were encountered. In the study, size distribution analysis using terrestrial laser scanning technology (LiDAR) was firstly applied to laboratory scaled broken rock pile, and then, the method was applied to aggregate pile and blasted rock pile in a quarry. Particle size analysis process contains; obtaining point cloud data of the piles using terrestrial laser scanner, creating three-dimensional computer models of the piles through the various filters and related software, defining the fragments and determining the particle size distribution. It is concluded that LiDAR technology can be used effectively in the determination of the size distribution of the piles for evaluating the blasting results.
