Open-pit mining has increased substantially over the past two decades. Many currently operating open-pit mines are facing the end of mine-life over the next few decades and, increasingly, focus is shifting towards mine-closure planning that provides evidence on available closure options under the given geological, hydro(geo)logical and climatic conditions. This …

The abandoned open-pit mines were generally small in area, with a total area of approximately 120.56 hm 2 (Table S1). These abandoned open-pit mines were first mined from the 1980 s to the 2000 s and contain three types of resources: construction sand, tile clay, and granite ore for construction (Fig. 1). Construction sand is generally obtained ...

The stability of open-pit mine slopes is crucial for mining operations and is a prerequisite for the safe, efficient, and economically viable extraction of resources [1], [2], [3]. Slope-related disasters citing open-pit coal mines have been frequently reported. For example, a massive landslide occurred at the Bingham Canyon copper mine in Utah.
