Abstract:Purpose: The treatment of complex old concealed goaf has always been a major problem in open-stope mining. To solve the safety management problem of large area, multi-middle section, and collapsed old hidden goaf in Shishudi Gold Mine. Method: Through the investigation of the characteristics of goaf, the research and engineering application practice of paste-like non-cemented filling treatment technology for the high stagelarge-span subsidence goaf was carried out. Result: The non-cemented full tailings filling was used to control the goaf, which eliminated the hidden safety hazards of the old hidden goaf, prevented the continuous settlement and collapse of the surface, and avoided large-scale ground pressure disasters. Conclusion: The research on the treatment of goaf by non-cemented full tailings filling has great economic and social benefits for reducing the operation cost of the mine and realizing the zero discharge of solid waste in the mine, which provides a reference for the treatment of goaf in the majority of domestic open stope mining mines.
