Title: Transition From Open Pit to Underground Mining Through Diamond Room Filling System
Abstract:The combined oPen pit and underground mining system has found wide application in depeit mining.

However,very thick safety pillars are usually required between the open pit and the underground stopes. Technologically, it poses great difficulty in mining these pillars,especially when the mining conditions are very complicated. In this paper, an innovative mining system is presented which consists of diamond room sublevel stoping and backfilling. Using this system,artificial safety pillars are constructed between the open pit and the underground stopes so that transition to underground mining can take place directly. This system can be used to mine either stable or unstable oretalies.Read More
