The article presents the results of research work that provides a correct solution to the problem of assessing the quality of drainage water that is formed in the process of coal mining. In the context of this problem, the following main tasks have been solved: - assessment and ranking of technogenic factors of impact on the hydrosphere of the region; - selection of the main parameters of the environment for the development of research methods; - formation of models to substantiate the quality control of drainage waters. The authors of the article have developed scientific and technical solutions that represent an objective basis for interpreting research materials on the territory of a coal-mining region. The article presents the main results of the system analysis of experimental and theoretical studies. In particular, the authors show that the main types of models should be models of objects - sources of pollution, models of technogenic impacts and a model of a natural and technical system.

Information was collected on the multi-apartment housing stock of six mining towns in the Rostov region: Gukovo, Donetsk, Zverevo, Kamensk-Shakhtinsky, Novoshakhtinsk and Shakhty. A general analysis of emergency residential buildings was carried out in accordance with the year of construction and the number of buildings commissioned and square meters of living space. In the example of the city of Shakhty, the location of the emergency houses relative to the mining zones at shallow depths, the spread of loess subsidence soils, and possible flooding is discussed in detail. Thanks to the map created with the help of the GIS program SAS.Planet, conclusions are drawn about the location of the emergency structures. It is determined that the largest number of houses that are recognized as unfit for further exploitation are located within the distribution zones of the three negative factors listed above or in the immediate vicinity of them.
