Study on Stability of Surface Mine Slope Influenced by

As a result, underground mining is often used. The endwalls of surface mines will suffer double disturbance of surface mining and underground mining, with the coal mined by the latter. And it will influence the slope stability, surface mining and transportation safety, bringing a new research topic of surface and underground mining.

Mining Underground mining | Britannica

Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the surface.

With the continuous surface mining of mineral resources, open pit slopes become higher and steeper, potentially leading to instability. In addition, with depletion of near-surface mineral resources, surface mining becomes more costly. Obviously, to ensure mining safety and efficiency, underground mining is an alternative choice.
