Complete technology and application of fine-grain tailings mould bag dam

The project of “Fine Grain Tailings Mould Bag Method Dam Completion Technology and Application” undertaken by Mining and Metallurgy Group has reached the international leading level

Recently, the "Fine-grain tailings mould bag dam complete technology and application" project undertaken by Mining and Metallurgy Group successfully passed the expert review organized by China Nonferrous Metals Industry Association. After a comprehensive review and unanimous evaluation by the expert group, this achievement has reached the international leading level and has a good prospect of promotion and application.
Experts inquired and communicated the project and formed a comprehensive evaluation conclusion. It is concluded that the project has systematically carried out a complete set of technology research on fine-grained tailings mould bag dam construction, and formed a series of technical achievements in response to many key technical problems faced by fine-grained tailings dams. The main innovations include: Innovatively put forward the complete set technology of fine-grained tailings mould bag dam, the mechanism and the failure mode of the stability of the mould bag dam body, the mechanism and process of the stability control of the mould bag dam under multi-factor coupling Optimized measures, and on this basis, developed a new method for safety and stability evaluation of the fine-grained tailing sand bag method dam and new equipment for automatic grading dam construction by the mould bag method, which successfully solved the difficulty of fine-grained tailing dam construction Satisfy technical problems such as production at the dressing plant, high dam infiltration line, insufficient flood control storage capacity, low safety stability, etc., widen the scope of application of the fine-grained tailings dam particle size, the optimization of the process improves the automation of the mold bag dam The level improves the efficiency of dam construction and guarantees the safe operation of fine-grained tailings dams. After the application of the project achievements, it has generated a total of 4.57 billion yuan in economic benefits, and created significant safety, environmental protection and social benefits. It has helped China's tailings pond industry to develop in an innovative, integrated, green, and intelligent way. Disposal and solution of solid waste storage problems with similar conditions play a role in demonstration.
