Technologies for the disposal of industrial waste in the production of building materials are becoming particularly relevant in connection with the global trend of systematic reduction of the negative anthropogenic impact on the environment. Therefore, one of the goals of the pilot project of the innovative coal-watercoal cluster of housing and communal services is the utilization of ash waste from the combustion of coal-water fuel suspension in the production of building materials. The methodology of ash waste disposal consists in the modification of Portland cement with fine fly ash additives in the production of heavy concrete. As a result of the experiments, the authors proposed a recipe for a concrete mixture with ash waste additives. Tests of control samples of concrete and proposed samples of ash concrete with the addition of ash from the combustion of coal-water slurry were carried out. The brand of the proposed ash concrete in terms of compressive strength, corresponding to the design brand, is determined. Thus, we save the consumption of Portland cement as a binder, which is the most expensive component of concrete. At the same time, we dispose of man-made waste as a safe additive in the production of concrete with specified performance characteristics. The result obtained with the utilization of ash waste as an effective and safe aggregate for heavy concrete can be used in the implementation of a pilot project of an innovative coal-watercoal cluster of housing and communal services. Ash concrete with the addition of ash from the combustion of coal-water slurry can be recommended for use in industrial and civil construction.

“…Widely used sanitary standards in Russia as well as in other countries have certain limitation for generalized assessment of the territory ecosystems environmental security level. The problem of maximum permissible environmental load assessment has been extremely important at the moment [5][6][7][8][9][10], although this problem research analysis allows stating certain fragmentation in its solution.…”

The environmental threats and risks assessment is carried out on the basis of various anthropogenic criteria analysis. It’s reasonable to assess certain environmental indicators for each type of technogenic danger. The problems of the maximum permissible environmental load assessment and the development of the regional environmental security assessment methods have been actual. Therefore, the aim of the article is to develop the basics of the regional environment security level assessment methodology. It’s expedient to assess certain partial environmental indicators for each type of technogenic hazard. Such partial indicators were analyzed by statistical methods. The integration method was used to develop partial and integral indicators for assessing the regional environmental security level. The result of the research is proposition to assess the regional environmental security level by two groups of environmental factors: 1) antropogenic substances ingress into the environment and 2) natural systems change, caused by natural resources consumption and spatial planning factors. Application of the regional environmental security assessment methodology will allow to formalize environmental management problems by using the following indicators: integral environmental security indicator of reducing the anthropogenic substances ingress into the environments (II1) and integral environmental security indicator of reducing natural system change, caused by natural resources consumption and spatial planning factors (II2).

One of the factors in the formation of the ecological state of a city is the planning scheme of development, reflecting the features of the functional division of city space. At the same time, ensuring environmentally safe urban space involves solving the engineering problem of layout adjusting (optimization, modernization), taking into account the natural factors (terrain, landscape, climate zone) and the economic specialization of the territory. In this context, comprehensive environmental studies should be carried out, the main objective of which is to identify patterns of formation and manifestation of violations of environmentally safe environmental parameters (pollution of soil, air, water, including underground and above-ground sources, sea) in order to overcome or reduce negative processes in the present or in the future. The geoecological mapping of environmental risks in different areas of the city based on the seaside recreational area-Feodosia.
