The current pace of construction leads to the use of large volumes of construction raw materials, which must meet the regulatory indicators, including radiation. High levels of natural radionuclide activity, both in construction and finishing materials, affect changes in the gamma radiation indicators in the premises, which can negatively affect th...

The area of natural saline lands in Russia is about 30 million hectares. At present, the growth of technogenically saline areas is associated with the extraction of minerals (agro-ore) and the formation of drill pits when drilling wells for the purpose of exploration and production of hydrocarbons. The number of drilling pits with a high salt conte...

During the development of the oil and gas complex in conditions of Western Siberia the acute problem raises with the bore mud recultivation. The amount of mud storage pits in Khanty-Mansiisk autonomous district reaches three thousand, analogous situation is also in YNAO. The bore muds have negative physical and chemical properties, such as ash stru...

This paper analyzes the radiation status of environmental components on the underground nuclear explosion site codenamed Tavda, which is located in the Nizhnetavdinsky District of Tyumen Oblast. This underground nuclear explosion occurred in 1967 and was part of the Program #7 Nuclear Explosions for the National Economy; it is currently one of the...
Article
It was found that an underground nuclear explosion at a depth of 172 meters with a charge power of 0.3 kT, carried out with the aim of creating an underground reservoir for storing hydrocarbons, for a 53-year after-effect period is associated with a high content of technogenic radionuclides in the soil profile. With the indicated charge, power and...

Because of the growing mining of raw hydrocarbon deposits one observes the increase in the volumes of bore mud accumulation. By their chemical composition and hydrophysical properties they have a range of negative characteristics, such as high alkalinity and toxicity, lack of structure, hydrophilic nature, low airing, filterability etc. The indicat...

The problem of rational use of saline soils, as applied to the specific region, becomes one of the most important in Russia as well as abroad. The article reflects potential possibility to include these soils in the development of urban environment. This will allow us to extend the degree of use of the demographic capacity, as applied to the Siberi...

The negative physical properties of drilling cuttings are caused generally by the presence of large amounts of exchangeable sodium. Its sources are boring solutions with the use of caustic and soda ash and also the saline rocks extracted in the process of drilling. Drilling cuttings have lack of structure and swelling in the wet state, adhesiveness...

The article reflects negative physical and chemical properties of the bore muds in respect to Tyumen region (high dispersion, swelling ability, ash structure, crust formation, low filterability, a high degree of salinization, alkalinity and toxicity). Indicated properties are mainly stipulated by the increased content of exchangeable sodium in the...

Drilling of wells is connected with formation of the bore mud represented by the drill cutting with waste drilling mud. Bore mud has negative physical-chemical, physical and chemical properties: high content of salts, increased alkalinity, ash structure, soil overcrust, low airing, weak filterability and so on. In case of phosphogypsum adding to th...

The article considers the results of studies of the chemical and granulometric content and the factor of bore mud filtration in the process of its utilization. When the phosphogypsum is added, hydrophysical properties of the bore mud improve. At the same time, gradation of soil from the water-proof to weakly permeable takes place. This phenomenon i...

The article considers biogeochemistry of heavy metals in the system soil-plant-animal in the terms of the south of Tumen region. The results of researches showed that soils are impoverished by the active forms of zinc. Its average content in the soils was 0.62mg/kg that is below normal for the provision of all group of plants. The regions with rela...
Article
The paper presents the study on the physical properties of the cuttings. Culvert capacity of the drill cuttings with different coagulants is considered. The water permeability of the studied samples varies depending on the quality of the composition and the dosage of a coagulant used. The coagulants have been proposed as aluminium sulphate, iron su...

The article presents a study of the radiation and geochemical background state of soil in the south of Tyumen region. According to the obtained data it was revealed that within the study areas, the power values of gamma radiation exposure dose ranged from 6 to 12.5 mcR/h, due to the natural gamma background of the area. The research results of the...

... As can be seen from the above, in order to optimize pH level of digestion mixtures, C/N ratio and dry matter content, various types of organic waste must be used simultaneously. As a result, at the second stage of investigation, the optimal ratio of waste components in mixture was determined so that C/N ratio was optimal for the methanogenesis process [3, 21,27]. As seen from Fig. 5, digestion of mixture of fecal sludge, poultry manure, cattle manure and sewage sludge (FS + PM + CM + SS) provides biogas yield of 18 ml/g (dry matter) in 14 days. ...
... На сегодняшний день экологизация земледелия, ресурсосбережение, сохранение окружающей среды являются актуальными научно-практическими проблемами не только у нас в стране [12,13], но и за рубежом [14][15][16]. В степной и лесостепной зонах Западной Сибири основу пахотного фонда составляют черноземы -самые ценные пахотнопригодные почвы региона. ...
... The use of such soils as a basis for roads, without proper techniques to prevent the occurrence of swelling, leads to serious destruction of the roadway or its slopes. The construction of the roadbed in such conditions forces the road builders to replace the weak ground base with the entire thickness of the sandy ground, which has a high filtration coefficient and a low capillary rise height [3,4,5]. This method of the roadbed building significantly increases the time and cost of roads construction. ...
... Tanto en los jales, en el ecosistema de referencia, como en áreas vecinas es necesario conocer la composición de las especies vegetales y animales , la diversidad biológica, y las principales interacciones entre los organismos . El conocimiento de las interacciones entre especies vegetales establecidas en el jal con especies animales es importante para evaluar la introducción de los contaminantes en la cadena trófica (Skipin et al., 2016;Galván Ramírez, 2020). La evaluación ecológica rápida a escala local debe considerar la identificación de los organismos cuyo ámbito hogareño incluya la interacción con los jales (Esteves Aguilar, 2018;López Michelena, 2021) (Fig. 6). ...
... The migration of toxic salts of components (ions of chlorine, sodium, sulfate ions, hydrogen bicarbonate ions) and oil products, both in vertical and horizontal directions, leads to deterioration of soil properties: the waterair regime of the soil is disturbed, the concentration of soil solution increases, sodium in MAC, microflora is inhibited, which makes the soil unsuitable for plant growth. This leads to the destruction of existing ecosystems on the territory, followed by contamination of adjacent environments [11,12]. ...
... Analysis of transformation and evolution of soils that are involved in agriculture is traditionally in the center of attention of genetic soil science and has an important applied significance for agricultural environmental optimization and adaptation of the modern agricultural systems to the conditions of a certain agricultural landscape [11]. Rationale for the studies of black soils of Western Siberia is determined by prevalence of young (compared to the European Russia) topsoil that has only recently found use in agriculture. ...
