Rock dumps of coalmines have high potential for forest regeneration and environmental capacity, which are dependent on the technology of reclamation and the properties of technogenic soils and grounds. Traditional forestry methods for obtaining the main criteria of biological indicators of woody vegetation were used in the study as follows: ground seed germination, seedling planting technology, composition and increment of tree stands, root structure, care harvesting of undergrowth, biotopic classification. Natural overgrowing of dumps is dependent on the availability of seeds and conditions for their germination and subsequent growth. Most of the zonal tree and shrub species are able to colonize and grow on the coalmine dumps. Mineralization of the dumps surfaces without rich soil stratum, porosity of the upper horizon of lithostratum, and low nutrient content (nitrogen) give benefits in the growth and subsequent formation of birch, pine and sea-buckthorn stands. Afforestation is the cheapest and most effective method of biological reclamation. The analysis of artificial reforestation shows the probability of targeted plantation cultivation of various tree species. The use of a wide range of tree and shrub species make it possible to create biologically diverse intrazonal technogenic ecosystems with high recreational and economic productivity. Wildfires spreading out in spring season on herbaceous rags limit the overgrowth of the dumps by forest vegetation. Two-year cyclical increment decline of trees due to provocative spring warming takes place. The zoogenic factor, especially zoo chores distribution of berry plants, has essential value for forest forming process. By the results of forest formation analysis at rock dumps, alveolate-hilly technology of mine reclamation was developed, which allows to significantly improve dumps’ afforestation capacity, their biological posttechnogenic diversity and productivity.
