Mmezu nke ọma nke 2700 Ton Ultra-large Electric Shovel Synchronous Lifting Project na Mongolia

Oyu Tolgoi Copper Mine (OT Mine) bụ otu n'ime ogbunigwe ọla kọpa kachasị n'ụwa yana ogidi akụ na ụba dị mkpa nke Mongolia. Rio Tinto na gọọmentị Mongolian nwere 66% na 34% nke mbak n'otu n'otu. Ọla kọpa na ọla edo nke ogbunigwe ọla kọpa mebere bụ 30% ruo 40% nke GDP Mongolia. Ebe ogbunigwe OT dị ihe dị ka kilomita 80 site na oke ala China na Mongolia.
