tailing dam mining

Tailings dam Wikipedia

The standard of public reporting on tailings dam incidents is poor. A large number remain completely unreported, or lack basic facts when reported. There is no comprehensive database for historic failures. According to mining engineer David M Chambers of the Center for Science in Public Participation, 10,000 years is "a conservative estimate" of how long most tailings dams will need to maintain structural integrity. The lack of any comprehensive tailings dam database has prevented meaningful analysis, either gross
