The technique of identification of dam fill hydraulic conductivity based on correlation analysis of piezometric readings is proposed. Contour maps of groundwater levels were examined. As well as simulation modelling was performed in order to determine the most probable seepage computational model of earth dam corresponding in the best way to monitoring data. While simulating special attention was being payed to seepage control and drainage features performance. Thus it was approved that earth dam seepage regime meets the criteria of safety against seepage.","PeriodicalId":313972,"journal":{"name":"Environmental safety and natural resources","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127065097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attempts to obtain the correct method of calculation led to the emergence of a large number of methods, methods of calculation and calculation schemes: their diversity is explained by the number of assumptions used by researchers to justify the calculation scheme and stability conditions. The task of determining the parameters of a steady slope or bearing capacity of the base in most cases is statically uncertain. Therefore, for the determination of unknown reactions, the authors put forward additional conditions (assumptions). The variety of existing methods for calculating the stability of slopes caused the need to classify them by one or another feature. Based on a detailed analysis of work in this area, four groups of basic assumptions put forward by researchers for substantiation of the calculation scheme for calculating the stability of slopes, obtaining stability conditions (equilibrium) of the shift prisms, the selection of the shape and position of the weakest surface of slip in the slopes were identified. These are assumptions such as: about the condition of the boundary stress state at each point of the bias prism (the method of the boundary stress state); about the distribution of normal reactions along the surface of the slip (methods of a monolithic compartment of collapse, that is, when considering the balance of the prism of the shear completely); the ratio of tangential and normal reactions at the lateral sides of the compartments (the reaction is horizontal, inclined or marginal rejected); in relation to the shape and position (geometry) of the potential (weakest) surface of the slide. In conclusion, it was concluded that the method of the boundary stress state is most useful for preventing collapses, then studying the shape of slopes and external loading, at which a possible collapse. The method of boundary equilibrium, in turn, is desirable to use for the analysis of a strained state of landslides.","PeriodicalId":313972,"journal":{"name":"Environmental safety and natural resources","volume":"589 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132593238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the work is to assess the environmental hazard of the territory of the Rozdil State Mining and Chemical Enterprise \"Sirka\". The research was carried out on the territory of Rozdil SMCE “Sirka”. Rozdil State Mining and Chemical Enterprise “Sirka” is in the West of Ukraine (Lviv region) of the Dniester River basin. According to the State Register of Potentially Hazardous Objects (PHO) of Ukraine, Rozdil State Mining and Chemical Enterprise \"Sirka\" belongs to the monitoring facilities of PHO. The X-Ray Diffraction (XRD) method was used experimentally to determine the qualitative and quantitative composition of heavy metals and other inorganic elements in samples, soil pollution with heavy metals. The main threats were identified which should be considered at the stage of liquidation of the mining and chemical enterprise. The main reason for pollution of the water objects of the enterprise territory and the Dniester River is the non-performance of the project on maintenance of ecological balance, monitoring, reclamation of the territory of the land due to lack of financing for the implementation of projects. In this regard, sources of pollution (phosphogypsum, oil tars, lump sulfur, flotation tails, solid waste) constantly affect the environment and over the years the situation is still dangerous. On the example of Rozdil State Mining and Chemical Enterprise \"Sirka\" the main problems of the monitoring system of the territory of the mining and chemical enterprise at the stage of liquidation are demonstrated. The influence of the mining and chemical enterprise on the state of pollution of the environment: soil, water environment, and waste management status were also assessed. Also, according to the obtained data, in the man-made reservoirs of the enterprise (Lake Hlyboke, Lake Serednie, Lake Chyste, channels), which flow into the Dniester River, an excess of the MPC is seen in many hydrochemical parameters: pH, sulfates, phosphates, ammonium nitrogen, etc.","PeriodicalId":313972,"journal":{"name":"Environmental safety and natural resources","volume":" 19","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120829931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
