Basic dependencies in the development of the front of work at the open pits, dangerous by landslides
Abstract
Tikhvin bauxite deposits, on the example of which are considered dependencies in the development of the front of work at open pits, dangerous for 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 works are carried out by one ledge, sometimes with division into sublevels, using upper and lower loading by excavators with buckets of 1-4 m3. The thickness of covering rocks is characterized by layered structure, change of lithological composition in transverse and longitudinal directions, fall of clay layers in some areas towards the mined-out space of the quarries, as well as watering of gravelly pebble deposits, sands, fractured limestone and bauxite rocks.
