Tailings can be stored below ground in previous worked out voids. The tailings are generally mixed with a binder, usually cement, and then pumped underground to fill voids and help support an underground mine. For example a ‘room and pillar’ mining operation that uses backfill will be able to extract the insitu pillars containing ore.
