力拓（RIO.AX）、（RIO.L）周五表示，在发生地震事件导致采矿活动暂时停止后，该公司已完成安全审查，并已开始“逐步”重启其位于蒙古的奥尤陶勒盖铜矿的地下作业。
Rio Tinto (RIO.AX), (RIO.L) on Friday said it had begun "progressively" restarting underground operations at its Oyu Tolgoi copper mine in Mongolia after completing safety reviews following a seismic event that temporarily halted mining activities.
该矿商表示，10月29日发生的地震事件在生产区附近的一个临时储存区引发了局部岩崩，造成地面震动，但未对地下矿洞或运营基础设施造成结构性损坏。
The miner said a seismic event on October 29 triggered a localised rockfall in a temporary storage area adjacent to the production zone, causing ground vibrations but resulting in no structural damage to the underground cave or operating infrastructure.
奥尤陶勒盖是世界上已知最大的铜金矿床之一，对力拓的铜增长战略至关重要。该矿商持有该项目66%的股份，蒙古政府持有其余股份。
Oyu Tolgoi is one of the world's largest known copper and gold deposits and is central to Rio Tinto's copper growth strategy. The miner owns 66% of the project, with the Mongolian government holding the rest.
该矿商表示，有三名员工受伤，没有人员死亡报告，其中两人因非危及生命的伤势继续接受治疗。
The miner said three employees sustained injuries, and no fatalities were reported, with two of them continuing to receive treatment for non-life-threatening injuries.
力拓还指出，所有通过中蒙之间甘其毛都边境口岸的车辆均受到影响而延误，这减少了从奥尤陶勒盖运输铜精矿的卡车可用数量。
Rio Tinto also flagged delays affecting all vehicles passing through the Ganqimaodu border crossing between China and Mongolia, which have reduced the availability of trucks to transport copper concentrate from Oyu Tolgoi.
