Open Cut and Underground Mining iMINCO

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 loion of the minerals. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead

Diamond Mining The Environmental Literacy Council

This includes not only saving the fill removed from the pit and refilling pits once mining has ceased, but also preserving topsoil to be redeposited on reclaimed land so that vegetation can be planted. In addition, diamond mining faces challenges relating to energy use and emissions which can contribute to the global climate change.
