What are the main methods of mining?

There are 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 Placer Get price

Block Caving

Block caving is an underground hard rock mining method that involves undermining an ore body allowing it to progressively collapse under its own weight It is the underground version of open pit mining In block caving a large section of rock is undercut creating an artificial cavern that fills with its own rubble as it collapses Get price

Subsurface Mining and its Environmental Impacts by Cayla

Transcript of Subsurface Mining and its Environmental Impacts - A form of coal mining where a long wall of coal is mined into a single slice typically about 0 6-1 0 meters thick - The coal is cut from the coalface by a machine called the shearer or power loader - Used to Get price

What are the pros and cons of subsurface mining?

Advantages of underground mining *less surface disturbance *less environmental disturbance *less waste mined per tonne of ore *ability to mine resources that are not economic as a surface mine *cheaper to set up mine development for deep ore depoGet price

Mining claim definitions

There are two types of mining claims lode and placer Lode Claims Deposits subject to lode claims include classic veins or lodes having well-defined boundaries They also include other rock in-place bearing valuable minerals and may be broad zones of mineralized rock Get price

The Environmental Science of Surface Mining

The environmental damage caused by surface mining is related to the large amount of surface material that humans remove during mining operations The environmental effects of surface mining include Habitat destruction Soil erosion Air pollution from dust particulates Pollution (especially from sediments) All surface mining techniques negatively affect the environment though some methods are Get price
