  • What are the main methods of mining? American

    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 mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.Coal mining methods LinkedIn SlideShare,Coal Mining is the term that encompasses the physical extraction or removal of coal from the Earth’s Surface. When coal is used as fuel in power generation, it is referred to as Steaming or Thermal coal while those which are used to create coke for steel manufacturing is referred to as Coking or Metallurgical Coal. Coal can be mined by both Surface and Underground Mining methods. Surface
