1 天前Openpit mining differs from quarrying (with the possible exception of iron ore) in that the valuable mineral constitutes only a small proportion of the total tonnage of rock produced In quarrying, the rock itself is the valuable commodity, with virtually all of the raw rock that is won being processed (often only by crushing and screening) to
Open Pit Mining Techniques|Surface Mines|Rock or
Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth

Open pit mining is considered different from quarrying in the sense that it selectively extracts ore rather than an aggregate or a dimensional stone product Open pit mining is applied to disseminated ore bodies or steeply dipping veins or seams where the mining advance is toward increasing depths
A new generic open pit mine planning process with risk
Conventionally, mining industry relies on a deterministic view, where a unique mine plan is determined based on a single resource model A major shortfall of this approach is the inability to assess the risk caused by the wellknown geological uncertainty, ie the in situ grade and tonnage variability of the mineral deposit Despite some recent attempts in developing
Opencast to underground iron ore mining method |
At the end of the openpit mining process in large metal mines, the mining model must change from openpit mining to underground mining, but the mutual interference between the two mining models leads to poor production safety conditions and difficulties in production convergence during the transition period To solve these technical problems of poor production
