Abstract:With the development of society, science and technology, the construction of green mines is in full swing nationwide. Digitalization of mines is an important part of green mines. Under the new situation, building a three-dimensional visualization model of mines is still an urgent task for mine technicians. Through the application of a mobile 3D laser scanner equipped with 3D laser scanning technology and a total station 3D laser scanner in a medium-sized copper mine, this article explored the advantages and disadvantages of the two methods and the scope of application. This technology can provide guidance for constructing the three-dimensional visualization.
