"WebApr 11, 2024 · When K ms > 1, the stability is good; mining only causes the loess slope to slip and does not induce landslides. When 0.95 ≤ K ms ≤ 1, the stability is poor and there is a potential risk of loess slope landslide induced by mining. When K ms < 0.95, the stability is very poor and the risk of mining induced loess slope landslides is higher. " - How does mining cause landslides
