Stability of Deep Excavation Slopes in Continuous Surface ...

2019-9-28  The paper investigates the stability of deep continuous surface lignite mining slopes. As excavation slopes are made relatively steep for exploitation purposes, the risk of slope instabilities is often appreciable, while the adverse consequences of a major failure are usually severe. Despite these, the design of lignite mining slopes against instability is often empirical, because the ...
