赞比亚穆富利拉铜矿是世界主要铜矿之一,1986年矿石产量为360万吨,入选原矿品位为2.07％,目前的矿石储量估计为8200万吨,矿石品位为3.07％。考虑到2000年以后该矿将进入深部开采和延长矿山服务年限,目前正实施一项重大的基建工程,即深部开采计划。Musombo SV1盲竖井的掘进便是这项工程的初期任务。该井从地表以下430米水平开始下掘,直径为6.7米,延深到1490米水平,总深1060米。掘进工作使用一台凿井抓岩机和一台凿岩台车。竖井提升能力为36万吨/月(矿石)和8万吨/月(废石);投入运转时,乘人罐笼可容纳200人,上下14个工作水平。
The Mufulila copper mine in Zambia is one of the world’s major copper mines. In 1986, the ore production was 3.6 million tons, the selected ore grade was 2.07%, and the current ore reserve was estimated at 82 million tons with an ore grade of 3.07%. Considering that the mine will enter deep mining and extend mine service life after 2000, a major infrastructural project, namely deep mining plan, is being implemented. The excavation of the Musombo SV1 blind shaft was the initial mission of the project. The well began to dig from 430 meters below the earth’s surface, measuring 6.7 meters in diameter, extending to 1490 meters with a total depth of 1060 meters. Tunneling operations use a rock-grab rocker and a rock drilling rig. Shaft lift capacity of 360,000 tons / month (ore) and 80,000 tons / month (waste rock); put into operation, riding cage can accommodate 200 people, up and down 14 working levels.
