block caving copper mining

The occurrence of the surface movement is the main focus of the study regarding to the gold copper underground block caving mining in Papua Indonesia The underground mining has brought some environmental problems on the terrain surface such as the lowering of the elevation followed by growing of the waste pile as the result from the failure of the rock slope In this study the surface

Application and research of block caving in Pulang copper

The application of block caving in mines shows significant advantages in large scale low cost and high efficiency thus block caving is worth promoting in the mines that meets the requirement of natural caving Due to large scale of production and low ore grade in Pulang copper mine in China comprehensive analysis and research were conducted on rock mechanics mining sequence

The least common method in hard-rock mining block caving is typically saved for low-grade ore It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse Gravity then takes over as the ore above the blast site fractures and collapses in succession as support is withdrawn The collapsed ore is hauled out the mine for processing [source

Block caving is a most cost effective underground mining method and it is expected as a major mining method in the near future by replacing large-scale/massive open pits where a risk of slope failure and waste/ore ratio is higher as pit depth is deeper The Northparkes Mines is well known as a pioneer of block caving mining in Australia and has ever produced copper-gold ore by using block

Block caving has been proposed for a section of the proposed Pebble Mine in southern Alaska to excavate a portion of one of the world's largest gold copper and molybdenum deposits Part of the Pebble deposit is buried roughly 1 000 to 7 000 feet underground This section is too deep for open pit mining and the developers have proposed to mine it by block caving
