what the basic knowledge to mining underground

Jim Herron of BLM inside dinero tunnel at 2000 feet during inventory and analysis. Credit: BLM. The mining process is used to separate rock or ore from surrounding rock. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. The method used depends onthe type of mineral resource that is mined, its location beneath the surface, and whether the resource is …

    Underground Mining. Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel, called a decline, is created to allow workers and machinery to reach the location of the minerals. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead and zinc.

    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.
