在开采30多年后,澳大利亚能源资源公司(ERA)已结束对Ranger矿的露天开采。对1#矿体的开采始于1980年,1994年开采完毕;1997年开始对3#矿体进行开采,2012年开采结束。如果市场条件有利,目前地表储存的矿石足够维持到2020年,或可维持到2016年,到那时,按计划将开始地下开采。
After more than 30 years of mining, the Australian Energy Resources Corporation (ERA) has completed its open pit mining of the Ranger mine. The mining of No. 1 orebody began in 1980 and was completed in 1994; No. 3 orebody was started mining in 1997 and ended in 2012. If the market conditions are favorable, the ore currently stored on the surface is sufficient to be maintained by 2020 or until 2016, by which time underground mining will begin on schedule.
