As paste technology can effectively ensure safe mining conditions and realize green mining, it has been popularized and widely applied in China in recent years. Meanwhile, with the development of intelligent control, precise preparation and personalized filling, studies on paste technology in China have also been deepened. In this paper, the basic concepts and characteristics of paste technology were introduced, and the development of paste technology in China was analyzed statistically. It systematically analyzed the latest research progress in thickening dewatering of unclassified tailings, pipeline transportation of structure flow, multi-field influence in stopes, development of new materials and construction of paste engineering laboratory. The practical effects of paste technology in underground backfill and surface deposition were also introduced. In the future, paste technology will achieve great breakthroughs by digitization and intelligence and realize adaptive control of concentration, precision preparation of paste, personalized filling of stopes and 3D and modular design and assembly of system, leading mining industry in China to the path of green development.
