Open Pit Mining - an overview | ScienceDirect Topics

An open pit mine could recover almost 90% of the oil shale in a very thick deposit [17]. It is said that strip mining could provide an even higher recovery. Shown in Fig. 8.8 is an open-pit mine used to explain the process of mining the oil shale. The overburden is drilled and blasted loose over an area above the oil shale zone and the load is ...

The challenge to SRK was to predict inflow to a large open pit mine from discrete, highly conductive faults then predict the behaviour of the post-mining pit lake. SRK undertook extensive hydrogeological studies at the Hycroft gold deposit that has culminated in predictive numerical groundwater flow models.
