Abandoned coal dumps have various chemical and mineralogical compositions. Under the
influence of internal and external physicochemical processes in combination with climatic and
hydrogeological conditions, the chemical composition of the dumps undergoes serious
transformations. This can lead to the inhibition of growth and death of plants that grow on the
dumps and adjoining areas. Therefore, the control of the state of phytomeliorants growing on waste
heaps is an important link to the rehabilitation of the mining territories
