Openpit mining Wikipedia
Open Pit Depressurization is the process of removing tensions or pressure from different areas of a mine Depressurization helps to make open pit mines more stable and secure By using an integrated mine slope depressurization Openpit mining is probably most advanced because of developments in mining lowgrade copper deposits and iron ore It is suitable for much of the resource if it is done on a large scale and will allow lowcost removal of most of the resourceOpen Pit Mining an overview ScienceDirect Topics
