Environmental pollution by industrial waste, including brown coal mining, is one of the environmental problems of many countries. To improve the ecological situation in the region, it is necessary to recultivate soils contaminated with brown coal waste. The goal of the study was to study the possibility of biorecultivation of soils polluted with brown coal waste from the Lenger deposit located in the south of Kazakhstan. It was found that the inorganic part of the brown coal waste is represented by minerals: Quartz SiO2, Gypsum CaSO4×2H2O, Kaolinite Al2Si2O5(OH)4, Cronstedtite Fe3((Si0.74 Fe0.26)2O5)(OH)4, Margarite CaAl2(Si2Al2)O10(OH)2, Muscovite H2KAl3(SiO4)3, Calcite CaCO3, Laumontite CaAl2Si4O12(H2O)2, Lead Aluminium Sulfate Hydroxide Pb0.5Al3(SO4)2(OH)6, with quartz con-tent in samples in the range of 61.5–92.9%. The organic part of the waste is 90.0% made up of humic acids and fulvic acids. It has been established that heterotrophic, cellulolytic microflora and micromycetes are represented by the genera Rhodococcus, Bacillus, Pseudomonas, Penicillium; Trichoderma, Dietzia, promising for biorecultivation purposes. The phytocenosis of coal waste dumps is composed of toxicotolerant ruderal plant species of the local flora: Centaurea scabiosa L., Centaurea iberica Trev., Cichorium intybus Linn., Cousinia cyrdariensis Kult., Achil-leamille folium L., Thlaspiar vense L., Arctiumto mentosum Mill., Onopórduma cánthium L., Agropyron cristatum L., Phlum pratense L., Erytrigia repens L., Nevski/Agropyron repens L.,Cynodon dactylon L., Capparis spinosa L., Polygonum aviculare L., Dodartia orientalis L., Althaea officinales L., Alhagipseud alhagi (Bieb.)Desv., Peganum harmala L. For biorecultivation of soils contaminated with brown coal waste, an algorithm of work has been devel-oped, including the use of soil blocks with integrated seeds of toxicotolerant plants inoculated with microorganisms.
