  • What are the main methods of mining? | American

    There are four main mining methods: underground, open surface (pit), placer, and insitu mining Underground mines are more expensive and are often used to reach deeper deposits Surface mines are typically used for more shallow and less valuable deposits Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environmentsLarge scale mechanised mining methods we use include: longwall mining, where a long wall of coal is mined in a single slice, usually by a large machine sublevelcaving, where levels of the ore are blasted by explosives; and ; block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity We use these three different types of underground miningDigging deeper: Mining methods explained | Anglo AmericanThe mining industry applies softwarebased computerized extension functions for estimation of acceptable mine production block/subblock grades based on the principle of gradual change Inverse power of distance or (1/D n) interpolation is the preferred methodMining Industry an overview | ScienceDirect Topics
