Areas of self-attack of coal industry dumps in the dry-steppe sub-zone of Khakasia, forest-steppe sub-zone of Krasnoyarsk Krai (KATEK) and subtaiga sub-zone of Kemerovo region (Kuzbass) were investigated. Ecologicalcenotic characteristics of herbaceous communities are studied at application of fertile flat of soil and on manmade elution without application of soil-improving agents. Former arable land of the appropriate age is chosen as a control in each late. Geobotanical descriptions were carried out according to standard methods taking into account several repeats, floristic lists were processed using IBIS software. There is a decrease in species diversity as the aridity of the subzone increases: 38-52 species by habitat types are noted in the subtaiga, 34-40 species are noted in the forest-steppe, 20-31 species are noted in the dry-steppe. It has been established that in all three zones on the dumps the ecological-cenotic structure of grass communities of dumps is shifted by one step towards xeromorphism: on the dumps of the subtaiga late there are formed meadow phytocenoses, forest-steppe meadow and meadow-steppe phytocenoses, in dry-steppe – ruderal phytocenoses. Application of fertile soil layer contributes to increase of herbal parameters: in the subthareal zone on such areas species abundance is 18% higher than on deposits, and in the dry-steppe subzone projective coating is 33% higher than on man-made elution without application of soil emitters. Thus, the presence of a humus horizon contributes to the acceleration of the formation of herbaceous ecosystems, but is not an unconditional factor in their achievement of the stage of zonal formations
