Abstract:
Dundee Precious Metals Chelopech, gold/copper mine is an underground operation located adjacent to Chelopech village in Bulgaria. This paper presents a summary of the successful progression of Chelopech Mine from a 0.5 Mtpa sublevel caving operation to the current 2 Mtpa long hole open stoping operation with paste fill. It discusses the utilisation of various types of mine fill including cemented rockfill (CRF), cemented hydraulic fill (CHF) and paste fill. This paper also describes some of the significant challenges faced and several of the critical aspects of mine fill design, implementation and operational management.
