Abstract: With the gradual strengthening of the state's supervision of the geological environment of mines，monitoring of the geological environment of mines has become an important daily work of mining en⁃ terprises. Taking the geological environment monitoring of Sifang Gold Mine as the background，this paper proposes a monitoring method that combines UAV PPK image-free aerial survey technology and data visual⁃ ization technology，which provides a new idea for mine geological environment monitoring. The results show that the current UAV PPK free image control aerial survey technology can meet the accuracy require⁃ ments of geological environment monitoring under complex terrain conditions. The monitoring results can be expressed in rich data visualization using GIS software to provide decision-making basis for disaster preven⁃ tion and control.
