A Cleaner Mining Method for Waste Tailings as Paste

A Cleaner Mining Method for Waste Tailings as Paste

Underground mining is the primary method to obtain economically valuable minerals, but it usually brings a large number of goafs (mined-out voids) and large quantities of waste tailings. The gradual accumulation of mine tailings has attracted worldwide attention because of its occupation and acidification of land, and a large number of goafs often lead to stope instability and ground subsidence.
