奥林匹克坝Olympic Dam Mine） 网址：/bb/ourBusinesses/baseMetals/olympicDam/aboutOlympicDam.jsp Located 560 kilometres north of Adelaide, South Australia, Olympic Dam is a multi-mineral ore body. It is the worlds fourth largest remaining copper deposit, fifth largest gold deposit?and the largest uranium deposit. It also contains significant quantities of silver. Olympic Dam is Australias largest underground mine. Most of Olympic Dams employees live in Roxby Downs township, about 16 km south of the operations. The township has a population of about 4 000. Olympic Dam has about?1 500 permanent employees and 1 500 contractor employees. 奥林匹克坝铜?-?铀矿-?金矿床位于澳南部阿德累得市以北约560km?(30°25′?S、136°45′E)奥林匹克坝奥林匹克坝Roxby Downs小镇，这个小镇大约有4000口人，位于矿山南部16km处。奥林匹克坝The Olympic Dam underground mining operation is highly mechanised, with automated rail transportation and underground crushing. The primary method of ore extraction is long hole open stoping with cemented aggregate fill. This method allows for large equipment to achieve high productivity and maximum ore recovery. 奥林匹克坝“Olympic Dam铀-铜-金矿床采矿工艺” Resource estimates and production statistics（储量估算和生产能力统计） Production(生产能力 2005-06 2006-07 2007-08 2008-09 Refined copper(精炼铜 198 735 t 172 063 t 169 900 t 194 100 t U3O8(八氧化三铀 4145 t 3455 t 4144 t 4007 t Gold(金 102 179 oz 85 599 oz 80 517 oz 108 000 oz Silver(银 843 330 oz 776 673 oz 780 000 oz 0 oz Olympic Dam Expansion：The proposed expansion is likely to see the current underground mining operation eventually converted to open pit. If the expansion proceeds, as a staged expansion, annual ore production will increase up to 70 million tonnes with copper production increasing from approximately 180 000 t a year to approximately 730 000 t.? 奥林匹克坝 另外，矿山业主为BHP?Billion?Ltd.）,?目前该矿采用地下常规方法开采，2008-2009年间将改为露天开采，改建后，该矿就会成为世界上最大的露天开采铀矿山（采场口大小为3?km×?4?km），矿体埋藏在地表以下350m，2005/7-2006/6澳财政年度的产量为3382tU3O8。 /operation/mountisa/ 芒特艾萨矿是一个年产矿石1000万t以上的地下矿山，全部采用充填法，是世界上年充填量最大的矿山。 采矿方法有空场阶段充填采矿法和机械化分层充填采矿法。 PDF文档“空场阶
