Basic dependencies in the development of the working face at open pits, prone to landslides
Abstract
Tikhvin bauxite deposits, on the example of which the relationships are considered in the development of the working face at open pits prone to landslides, are characterized by an irregular shape, a small width (an average of 200‑300 m) and a significant length (0.5‑3 km). Due to the small thickness of deposits, mining operations are carried out by one bench, sometimes with division into sub‑benches, using upper and lower loading by excavators with buckets of 1‑4 m³. The overburden sequence is characterized by a layered structure, change of lithological composition in transverse and longitudinal directions, dip of clay layers in some areas towards the mined‑out space of the quarries, as well as water saturation of gravel‑pebble deposits, sands, fractured limestones and bauxite rocks.
