Abstract:With the new concept of Digital Mine, mine management has urgent demands for 3D spatial information. 3D visualization management is an important component of digital mine. It is difficult for the current normal survey method to acquire data to meet the demand from 3D digital mine. 3D laser scanning, with the advantage of high resolution and non[CD*2]touch measurement, is suitable to acquire the 3D information on complex surface and dangerous area in mine. Based on the advantages of 3D laser scanning, this article discusses the application and method of this technology in mine, and gives a summary on the direction of its application in digital mine.
