The authors propose a simulation analytical model to predict the peaking of the organic material content in the formation of a biological geobarrier intended for the conservation of piled-up ore dressing wastes. The creation of artificial phytocenosis without fertile soil coating at the first stage of the biological geobarrier formation spurs the buildup of the biologically active medium due to the presence of a great amount of plant residue, which gives birth to trophic chains and initiates the migration of chemical elements in a biochemical cycle, as this is the main mechanism of natural landscape self-organization. Besides, the creation of artificial phytocenosis immediately puts an end any wind and water erosion, thus attaining the objective – conservation of piledup mineral material of man-made deposits. The article contains the estimates of the model parameters based on the data of the long-term monitoring of a biological geobarrier created for the conservation of apatitenepheline ore stripping wastes, and data of remote sensing of their location area with the use of geoinformation systems. The authors also predict the peaking of the organic material content with the biological organization of rock in the process of the biological geobarrier formation without fertile soil coating for the conservation of piledup rare-earth – rare-metal ore dressing wastes.
