The essence of subsidence and flooding of the territories was exa­mined. Using the route observation method, the phenomenon of subsidence and flooding within the Chervonohrad industrial mining region of the Lviv-Volyn coal basin was evaluated. The obtained results were compared with the data of geodetic monitoring and aerial photographs decoding. The intensity of subsidence and flooding of the surface was compared with the natural and technogenic factors. The classification of factors of subsidence and flooding of the coal mining area within the Chervonohrad industrial mining region of the Lviv-Volyn coal basin was carried out. Geological, climatic, and landscape factors were distinguished and grouped together as natural factors, while mining and residential factors were combined into a technogenic group. The selection of each factor is justified by the results of field and experimental explorations within the area of research. Relationships between factors of subsidence and flooding were established.

Basing on the mathematical model developed with the account of influence of bottom sediments, the parameters of benzene migration in the river caused by one-time discharge into the Stryi River were investigated,. The mathematical model of migration consists of two equations that describe the movement of pollutants in the river system, taking into account the flow rate, diffusion, sorption and desorption of the pollutant by the bottom sediments of the river. The parameters of benzene distribution in the "water-bottom sediments" system were experimentally determined under laboratory conditions. With the help of computer modeling, the temporal and spatial distributions of benzene in water and bottom sediments were obtained. The regularities of benzene concentration change depending on the composition of the bottom sediments of the river have been established. The dependencies can be extrapolated to other river systems and pollutants.

Transportation of oil and oil products through main pipelines is accompanied by the outpouring of these components into the environment, which creates risks of reducing the level of environmental safety and emergencies. The object of research is the factors and methods of environmental and civil safety management of cross-border transportation of oil and oil products through pipelines. Investigated problem is the analysis of environmental and civil safety management factors for cross-border transportation of oil and oil products through pipelines has been carried out and new technical and organizational solutions have been proposed to improve the level of management. The environmental safety of oil and gas facilities is defined as the state of environmentally safe functioning of oil and gas facilities and the absence of harmful environmental impact on these facilities. On the basis of the analysis of emergency situations on the linear part of the main oil pipelines, five main reasons leading to depressurization have been identified and ranked. The oil pipeline emergency is presented in a mathematical form. The analysis of depressurization of main oil pipelines in the world and in the Lviv region is carried out. The international normative legal acts regulating the management aspects of environmental and civil safety of cross-border transportation of oil and oil products are analyzed. Innovative products – in case of water pollution as a result of a catastrophic inflow of oil products, it is proposed to use a patented installation for modeling the process of pollution of running water and a method of physical modeling of the process of spreading pollution as a result of a single discharge of oil products into the river. In the case of soil contamination with oil products, it was proposed to use a patented installation for modeling the process of filtration of contaminated solutions through the soil or bottom sediments. The advantages of the proposed new technical solutions based on known analogues are shown. The area of practical use of the research results is the subdivisions of the Ministry of Environmental Protection and Natural Resources of Ukraine, the State Service of Ukraine for Emergency Situations, NJSC Naftogaz of Ukraine, higher educational institutions, research institutes of oil and gas ecological profile.
