  • Coal miningChoosing a mining method Britannica

    Open-pit mining. In open-pit mining of the coal seam several benches are established in both the overburden strata and the coal seam. The open-pit method is generally practiced where thick coal seams are overlain by thick or thin overburden it is also used for mining steeply pitching coal seams.

  • 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.

  • Basics of an open pit mine

    In a open pit coal mine the pit bottom would be the bottom mined coal seam elevation since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine the bottom of the pit would be the lowest level (elevation) that mining would be conducted on the ore being mined.
