Abstract: The article presents the study of parameters of technogenic eluvia laid at the stage of mining recultivation, in forest plantings on the dumps of the coal industry of Kuzbass of 25-45-year of age. The article considers features of architectonics of root systems of a pine in the conditions of various density eluvia of automobile, railway and excavator dumps with placing of potentially fertile breeds, a fertile layer of earth and without placing of any soil-improvers. It is shown that compaction technogenic eluvia leads to an underdevelopment of root systems and distribution of windfalls in plantings of this age group, the instability of such plantings at advanced age is predicted. It is identified that in case of friable summation of technogenic eluvia, the superficial-rod-anchor root system, classical for a pine, is formed irrespective of availability of a layer of soil-improvers. It is established that the forest plantings growing on poorly collapsing the large-size mountain substratum of excavator dumps are characterized by a reduced radial surplus of trees with low biological productivity. On the example of two sites with different properties of technogenic eluvia, the nature of influence of the endogenous fires of dumps on the condition of forest plantings has been analysed. In the conclusion, the basic principles are given directed on optimization of mining recultivation of dumps in order to form steady long-term forest plantings.
