Goaf Treatment for Gold Mine under Expressway
In recent years, the expressway construction in China is fast and more and more intensive network is formed, so it is inevitable that the technical problems on how to deal with goaf subsidence area at mine region is encountered. By thorough investigation and survey for underground goaf to ascertain its actual conformation and distribution, then by drilling and sand (water) injection, using dry-laid rubble to isolating filtration to treat border, back-filling spodosol into shaft etc, the underground gold mine goaf can be padded compactly, which will eliminate latent threats during expressway operation and which will achieve expected technical feasibility, economy, rationality, etc..
