Blockcaving definition is a mining in which sections of a large ore body are undercut by working places and then permitted to cave in, the ore so crushed being recovered through drifts.
Openpit mining is much safer than shaft mining. In underground mining, the threat of a cavein or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in caveins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.
cave mining—and block cave mining is the way of the future for many of Rio's large scale copper deposits. Total return (%) Block caving will only get more important. Rio is likely to have expanded block cave operations at Northparkes and new block caves at Oyu Tolgoi, Kennecott (KUC), Resolution and La Granja. The North Rim Skarn at KUC
MineTech International Conference and Expo, 24 November 2009, Johannesburg, South Africa Why Block Cave Mining? U/G mining method • Suitable for massive orebodies which have a large, regular "footprint" and either dip steeply or are of a large vertical extent. • By undercutting an area equivalent to the HR, caving is initiated.
