The article is devoted to the peculiarities of qualitative and quantitative composition of emissions in the production of building materials. This article describes a way of reducing dust emissions of solid substances pollutions exhausted in the atmosphere in the manufacture construction materials. The article focuses on the environmental problems of building construction industry. Volume of production of building materials is growing up and amount of dust particles substances in emissions around 5-8% every year at least both. One of ways to increase the environmental safety is reduction of dust emissions. Data on the relative content of some types of dust, typical for the construction industry in the total dust emissions entering the atmosphere of the city enterprises. The results of studies show that a significant content of fine particles, for example, 10 microns or less is concern in dust emissions systems of aspiration at the building construction enterprises. The great amount mention above of solid substances fine particles dimension involves the usage of special complex integrated analysis method of variance dust. The great amount mention above of solid substances fine particles dimension involves the usage of special complex integrated analysis method of variance dust. The value of the maximum permissible concentration of fine particles content by mention above dimension (around 10 microns) is less than for ordinary powder of building materials’ dusts. There exist and work a lot of building materials enterprises treat with bulk building materials in present time. It isn’t necessary to have ecological project of limitation emissions for small construction companies. So that this reason demands the improvement norms methodology for limitation for fine particles are concern in dust emissions systems of aspiration at the building construction industry. It allows preventing growing pollutions of atmosphere by emissions with fine particles dust.

This article describes a way of reducing dust emissions of solid substances pollutions exhausted in the atmosphere in the manufacture construction materials. The article focuses on the construction industry to improve the environmental safety improvement dust decreasing systems using complex integrated analysis method of variance dust emissions of dust aspiration systems. The article suggested developing a promising approach to improving the methods of complex analysis of variance with dust particles medium average rate (weighted average) parameters and integrated particle distribution function hydraulically equivalent size’ dimension and sedimentation’ time of dust samples investigated sample. Studies show that the use of response hydraulically equivalent size and the velocity of dust particles hovering sedimentation’ functions allow to obtain more reliable results of complex integrated analysis method of variance of the dispersion dust. At the same time developed using the results of such research and the complex devices used in combination of dry and wet cleaning can significantly reduce the amount of loose dust emissions in the production of building materials. The research’s results show that the integrated use of the devices dry and wet cleaning can significantly reduce the amount of loose dust emissions in the production of building materials. Reducing emissions of dust is one of the most effective reliable ways to implement environmental protection measures and to Increase of ecological safety of building materials industry treat with dispersion-bulk materials.
