Received: 16 October 2017 Accepted: 22 March 2018 Konkola copper mines (KCM) is an integrated mining operation comprising of open pit and underground mines (Nchanga and Konkola copper mines) Konkola mines is aptly referred to as Konkola deep and is, situated in Chililabombwe, Zambia. The mine is currently operating at 1150mL using sublevel mining method for copper ore bodies extraction. It intends to descend to 1500mL. There are various critical factors that influence a safe and economic design and dimensioning of a sublevel stoping method for underground extraction of metalliferous deposit. However, several mining operations maintain the same stope dimensions for all the sublevels rather than utilizing available design tools for example numerical modelling, empirical analysis etc. to optimize the operations. In view of this, a research study was conducted to optimize operational design and dimensioning of the stopes at 1250mL. The research mainly focused on the effect of variations in stope dimension to achieve better safety, economy and increased productivity
