A New Technique for 3D Laser Scanning of Cavities in Underground Metal Mines
Laser scanning technology is the most convenient way to move a 2D mine into a 3D world. Along with the 3D laser scanning technology development, Mine Surveyors now can obtain detailed 3D survey data images of underground production and development. Mine Planning/Engineering can use the data to determine the exact mined area, and to quantify the volumes of mined or unmined ore. And Rock Mechanics can use the data to predict rock failure. We carried on the laser survey experiment in the Guangxi Tongken Mine, and the result indicates that this method could survey the big cavities and the dangerous region effectively, moreover enhance the survey accuracy and precision. We could gain the cavity complex geometry information through the post-processing, including length, area, volume, changes of roof and rock and so on. The increased speed of remote data capture could contribute to a safer operation, and the increased quantity of data would lead to more accurate 3-dimensional models which could contribute to better reconciliation and mine design.
