The paper presents the results of research and assessment of the revegetation degree in reclaimed areas using coal preparation waste in the Kemerovo region – Kuzbass. Reclamation of disturbed lands was carried out by backfilling the worked-out pits of the former coal mine with coal preparation waste and forming a root layer on the leveled surface of the waste using materials of the fertile soil layer (FSL) and potentially fertile rocks (PFR). During the field survey of reclamation sites, it was found that when sowing perennial grasses (Bromopsis inermis, Medicago sativa, etc.) or planting trees and shrubs (Hippophae rhamnoides, Pinus sylvestris, etc.) on the formed root layer from the PFR and / or FSL, favorable conditions are created for the formation of the primary phytocenosis in the reclaimed areas. The studies also showed that in reclaimed areas using a fertile soil layer for the formation of a root layer, a gradual restoration of soil properties is recorded in the surface covered layers, which in some parameters are close to natural soils common in the adjacent territories.
