摘要：
According to the requirements of green mine construction and the coordinated development of environmental protection regulations, the existing filling technologies in China are compared and analysed. Several types of technologies are discussed, including the dry filling technology for gangue, grouting and filling for separated strata zones in overburden, grouting and filling technology for caving gangue fissures, paste and paste-like filling, high-water and ultra-high-water filling, and continuous mining and continuous filling. Then, the characteristics of these individual technologies are analysed. Through the analysis and comparison of these technologies, considering the requirements of green mine construction and coordinated development of environmental protection regulations, it was found that continuous mining and continuous filling technology is a feasible mean for constructing green mines and protecting the environment. In this study, the application of continuous mining and continuous filling technology in the Yuxing coal mine is introduced. Results show that surface subsidence was less than 80 mm, and the recovery rate of the working face reached 95%. This indicates that continuous mining and continuous filling technology can solve the problems of surface subsidence, environmental damage, and coal resource waste. Finally, the development prospects of continuous mining and continuous filling technology are proposed, providing theoretical and technical support for similar mining.
