At present an important ecological problem is the atmosphere pollution of the dust-ejection of a mining. One of the concerns exerting a negative influence not only on an environment but on a man is the Lebedinsk mine-concentrating concern, situated on Gubkin. The influence of it upon the environment is evinced by means of dusting the hillocks.
The problem concludes that the hillocks are fine-dispersive enough in its composition and after drying they are easy to be carried over with wind from the hillock´s surface, exerting negative influence on an environment and a man not only on the concern´s territory but close to the living houses. The hillocks of the Lebedinsk mine-concentrating concern contain in its composition of the order of 70% SiO2, about 10% FeO, 5% oxide Mg, also there are such biogenic elements in its composition as S, P, K, Ca. For an experimental study of the dust-carrying over of the hillocks of the LMCC the experimental plant was modeled and assembled. In the plant a constant speed of wind equal 12m/sec was founded and observed during all experiments.
The dust suppression was brought about two methods: mechanical and biological. Mechanical method concludes in a moistening the hillock´s surface to average moisture about 11%.
When the hillocks are in a moist condition, coefficient of the dust-carrying over is insignificant and composes 0, 34%, but in case with the dry hillocks it reaches 7%, it´s in 20 times more.
From literature it´s known that the biological method of the dust suppression is used in the concern and it spreads only on the slopes of dam, at present it concludes in the usage of the perennial shrubbery plants (sea-buckthorn). In our experimental work it´s studied the biological method of the dust suppression of all area of alluvium.
For the decrease of the quantity of the dust-carrying over the hillock´s surface the perennial sorts of beans and cereals were used as experimental seedling. The seeds of the cultures were sowed on the hillocks in Petri cups with the different masses: 100, 1000, 5000 kg/he of the hillocks. After the experiments and generalization of the experimental facts it can do a conclusion that the most optimal mass for the dust suppression of the hillock for the area 1 hectare is 1 ton of seedling, the most optimal studied cultures are cereals and it´s confirmed with the experimental facts.
As a result it was developed the technological scheme of the inculcation of the seedling in process of the magnetic separation.
The work was submitted to VIII international scientific conference «Ecology and environmental management», Egypt (Sharm el-Sheikh), February 20-27, 2008, came to the editorial office оn 16.01.2009.
