Mining paste filling is a structural flow filling method in which the filling material slurry is in the form of paste, and has a wide range of applications in mining operations. The following is a detailed introduction to mining paste filling:

Background of the proposal of paste filling technology

During the mining process, there have always been two major issues: safety production and environmental protection. In order to solve these problems, mines have adopted the method of backfilling solid waste into underground voids to prevent them from collapsing, thus giving birth to mine filling technology. As one of them, paste filling technology has gradually been widely used due to its advantages of good filling effect and high stability.

2. Characteristics of paste filling technology

Optimization of filling materials: The paste filling technology uses optimized filling materials with high strength and low permeability, which can meet the filling needs under different mining conditions.
Intelligent upgrading of equipment: With the development of technology, paste filling equipment is constantly being updated and upgraded, achieving intelligent and automated control, and improving filling efficiency and precision.
Environmental performance improvement: The paste filling technology can reduce the impact on the environment during use. The filling paste has high strength after underground solidification, and there is no weathering or release of toxic substances, which will not cause secondary pollution.
3. Application of paste filling technology

The paste filling technology has been widely used in the mining of metallic and non-metallic ores. It can not only effectively improve mining efficiency and reduce mining costs, but also solve the problem of solid waste disposal generated during the mining process, achieving resource recycling. At the same time, paste filling technology can effectively support goaf, reduce the risk of surface subsidence, and ensure the safety production of mines.

4. Development prospects of paste filling technology

With the global emphasis on environmental protection and efficient utilization of resources, paste filling technology has broad development prospects. In the future, this technology will continue to develop towards intelligence, high precision, and efficiency, continuously promoting technological progress and sustainable development in the mining industry. Meanwhile, paste filling technology will also be applied in more fields, providing strong support for solving resource recycling and environmental protection issues.

In summary, mining paste filling technology, as an important mining method, has significant advantages and broad application prospects. In the future development, this technology will continue to play an important role and make greater contributions to the sustainable development of mining and environmental protection.
