Mining is one of the foundation and pillar industries of China's national economy. There are more than 120000 mining industries in China, and the mining industry plays a very important role in promoting the development of the national economy. However, the mining industry not only provides materials for human beings, but also causes a lot of damage, including the discharge of solid waste, the most important of which is the discharge of industrial solid waste. The discharge of these wastes can induce environmental pollution, debris flow, tailings collapse and other safety hazards. Furthermore, underground mining has produced a large number of underground mined-out areas, which is the main cause of underground surface subsidence. Therefore, improper handling of tailings pond and goaf will bring great threat to the ecological environment and the safety of life and property.
The filling mining method can backfill the solid waste accumulated on the surface to the underground goaf, which can improve the safety of underground mining operations, prevent surface subsidence, and fill and utilize the solid waste on the surface, making it a safe, efficient and environmentally friendly mining method. The filling mining method has developed to the present, from the initial, for the purpose of dealing with waste rock, to the later development to improve the stability of the stope. Therefore, the filling mining method has become more and more important in modern mines. According to the different filling process and filling materials, filling mining method has developed from the initial dry filling to water sand filling, cemented filling, and then to paste filling. Each different filling method has different technical characteristics.
