Quarrying is a form of mining and is also known as open pit mining. When minerals are found deep below the surface a deep mine has to be dug to extract them. Quarries are usually dug deeper and larger until the mineral resource is exhausted. When they are no longer used quarries are often used as landfill sites for the disposal of waste.
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
