The object of research is a technology to produce physiologically active human materials from coal, methods for preparing aqueous solutions, the effectiveness of their impact on the seeds of wild plants, defined species of halophyte plants, which have been tested in harsh soil and climatic conditions of the arid zone of Kazakhstan where numerous processing factories of industrial production. The waste, so-called tailing dumps can catastrophically reduce the area of pastures, arable land and also cause various diseases of adults and children.
Therefore, the purpose of the work is significantly reducing dust and gas emissions from the surface of tailing dumps, rock dumps and ash and slag from thermal power plants by means of biotechnical reclamation, which involves sowing seeds of wild plants, after pretreating with a solution of a drug ‑ a plant growth stimulator obtained brown coal from the Kiyakty deposit.
The article presents the results of tests of an experimental sample of a preparation made from coal, as well as by the method of biotesting, the optimal concentrations of aqueous solutions of a humic preparation for treating seeds of wild plants, the optimal technological parameters for preparing seeds for sowing (duration of treatment with a humic preparation, seed maturation, etc.) have been determined: the optimal conditions for sowing seeds on the surface of the tailing dump (substrate moisture, temperature, salinity).
The installation of a pilot plant for obtaining a humic preparation was carried out, on which 550 kg of the preparation was obtained. Its chemical and toxicological properties have been determined; received a certificate of compliance with environmental standards. It has been established that the physiological effect of the drug is most effectively manifested on highly saline soils in extreme soil and climatic conditions.
The selected varieties of shrubs of alabota, wormwood, which give rapid growth on the surface of a dusty substrate, for example, at a wind speed of 2-10 m / s, the amount of dust emitted decreased by 85%.
