The types and sizes of open-pit mines are generally similar within the same mining area and generally have the same natural environmental background. In most mining areas, open-pit mining activities tend to be the most significant cause of land cover change (Xianju et al., 2016). Therefore, it is relatively easy to obtain better results in the ...

Open-pit mining is a type of surface mining. Instead of digging deep tunnels underground, miners remove layers of earth from the surface to access the minerals below. This creates a large hole or "pit," which can be several miles wide and very deep.

Open pit mining and quarrying operations represent a significant investment that needs to be managed over decades. Optimising performance and controlling operating costs are crucial, but any major change in use or increase to production capacity requires a further cash injection which can quickly escalate to millions.

Lines (50 m) were set up separately in plots A and B, and 50 quadrats (1 m × 1 m each) were prepared along the lines. The cover rate of each plant was evaluated and the mean cover rates were calculated. Numerous plant species were found at the study site, and plants with less than 1% cover rates are shown in the supplemental data (Table S1).
