The rapid development of spatial information technology, digital information technology, automation technology and intelligence technology has brought both chances and challenges for traditional mines. In recent years, the developed mining countries have applied information technology to reconstruct and promote their traditional mines. This work not only changed the traditional mining techniques and organization modes,but also greatly improved the production efficiency and safety level. Based on the achievements of the 86th Youth Scientists Forum of China Association of Science & Technology, which took digital mine as its topic, this paper introduces the concept and the framework of digital mine, the core theories and the technologies of digital mine, and the strategies and schemes for the implementation of digital mine. It is hoped that the study and construction of digital mine in China can be promoted and developed.
