Effective method of intensification of natural ventilation pits is to ensure steady airflow around the sides of the wind stream. Methodical features of the implementation of this method and the corresponding mathematical algorithm.
Results of field observation of atmospheric air pollution at a construction of transport tunnels on highway and railway Adler – Red Forest Meadow are presented. Features of an environmental pressure dynamics on atmospheric air are determined. The estimation of pollutant emission influence from transport tunnels on atmospheric air is given. Possibility of concentration of pollutants decrease in atmospheric air at the expense of ventilation shafts use for removal from the tunnel of outgoing air flow is shown.
The paper deal with the problem of developing a rational technology of slime and silt recycling for company «KINEF», which nowadays is one of the leading companies in Russia in it area. Therefore the question of soil-waste utilization is one of the major issues to adress for this organisation. During the reaserch samples of soil waste were taken and analyised, which helped to work out a complite technology of recycling. The technology of processing based on methods «wet chemistry» and hydrometallurgical processes. Special attention is paid to the necessity of extrac- tion of the useful components.
In this article a problem questions of diamondiferous rock enrichment wastes accumulation at M.V.Lomonosov diamond deposit, perspective ways of wastes utilization are stated. The current situation with wastes accumulation is passed in review. The technology of utilization is described in detail. The data on chemical composition, acid-base balance, ability to decrease soil acidity are given.
Activity of the Kovdor Mining and Processing Plant has a negative impact to the environment, particularly to the surface water. The results of hydrochemical analysis of the water samples allow to assess an anthropogenic load on the surface water and to upgrade the monitoring program.
