Mining Methods Now and in the Future - Advancing

The American Geosciences web site defines four main mining methods: underground, open surface (pit), placer, and in-situ 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.

Diamond Mining Methods Diamond Museum Cape Town

There are two types of pipe mining, namely open-pit mining and underground mining. Open-pit mining involves removing the layers of sand and rock found just above the kimberlite. Once exposed, the ore in the pit is broken up by blasting. A single blast can break approx. 3,000 tonnes of ore.

The optimization of mining method and equipment

Other Mining Methods. Some mining techniques — like in-situ leaching, which uses acid and water to remove minerals from a site without significantly disturbing the surface — have much less environmental impact. In-situ mining techniques can use less water than open-pit mining and underground mining, and also reduce the risk of releasing ore dust into the atmosphere.
