Abstract: As a kind of non-contact measurement technology，3D laser scanning technique has been widely used in mine surveying in recent years in China，involving slope monitoring in mining area，reserves management of open-pit mine，surface subsidence monitoring and other aspects of mine monitoring and research.Based on the analysis of the newly study results in recent years，the application status of 3D laser scanning technique in mine surveying in China is discussed，and some related existing problems are summarized.The study results show that the 3D laser scanning equipment and supporting software used in mine surveying engineering application and scientific study are mainly imported from abroad，and domestic equipment and software are few；from the aspects of data collection，processing and application of results，there are mainly problems in 3D Laser scanning technique for mine surveying，such as poor quality of collected data，low accuracy of point cloud data matching，low precision of point cloud data filtering algorithm，and inconspicuous results in special monitoring fields.Based on the above discussion results，further analysis results indicated that main study directions in the field can be summarized as following:①high-precision air-ground integrated data acquistion scheme，such as the integration of InSAR，LiDAR or oblique photogrammetry and ground based 3D laser scanning technique；②development of point cloud processing software with independent intellectual property rights，including point cloud data intelligent matching algorithm，intelligent high-precision point cloud data filtering algorithm；③late-stage application of 3D laser point cloud data，including deformation monitoring theory and method of ground planar objects，real-time dynamic monitoring method based on the integration of big data technique，artificial intelligent technique and 3D laser scanning technique.On the whole，further promoting the application of 3D laser scanning technique in mine surveying in China，is help for greatly improving the spatial 3D data processing ability of relevant engineers and technicians and increasing working efficiency.
