Jul 18, 2021 The anti-tipping stratum, at the front of the slope, was beneficial to the stability of the slope, playing a controlling role in its stability (Fig. 8). The disorderly open-pit mining of bauxite at the foot of the slope destroyed the structure of the anti-tipping strata and induced a loss of support for the slope.
