Abstract:In recent years, in order to maintain the sustained and stable high-speed development of domestic economy, a large number of natural resources have been exploited. With the deepening of the national ecological civilization construction, the standards and requirements to the environmental protection supervision have become more and more strict. In this context, many mines need to carry out ecological restoration work. Before ecological restoration, a lot of basic surveying and mapping work needs to be carried out. This paper takes the measured data of a mine in Jiangxi province as an example, systematically analyzes and demonstrates the advantages of digital-info topographic mapping and establishes the practice and effect of the actual 3D model of objects in ecological restoration.
