Drainage efficiency enhancement for watered sludge in Aikhal open pit mine

Abstract

The authors address the problem connected with gradual rise of sludge level in Aikhal open pit mine. It is found that sludge level has been rising gradually in the course of underground mining under the safety crown meant to prevent inrush of watered mud from the open pit bottom to the underground excavations. The promising approaches to steadying of watered sludge to ensure safe and convenient underground mining are developed
