Destructuring settlements due to frost heave during the structures’ exploitation are often not taken into account at the designing stage, although they are indirectly related to the bearing capacity of the soils. The objective of this research was analyzing the effect of the number of freezing-thawing cycles on the strength characteristics of soils. A paired experiment with various initial parameters (void ratio, initial moisture content, and the number of freezing-thawing cycles) was carried out. According to the experimental results, the cohesion largely depends on the above parameters which might lead to its decrease by up to three times. The angle of internal friction demonstrated an indefinite behavior during the freeze-thaw cycles, which is confirmed by a literature review. Freezing–thawing cycles significantly decrease the soil bearing capacity: up to 44% after 10 freezing-thawing cycles for soil with $e=0.55$ and $w=16.5\%$. However, in the case of $e=0.75$ and $w=22.6\%,$ it increased by 33%. A program based on the least-squares method was used to calculate the approximation coefficients of the dependence describing the changes in strength characteristics from the abovementioned parameters. Changes in strength characteristics must be taken into account when designing structures, as they can lead to additional settlement or even subsidence of the foundations.

Based on scientific research and experimental tests, it has been proved that solid waste from oil fields in the Kyzylorda region based on asphalt resin paraffin sediment (ARPS) is close and binding in its chemical composition to the main component of the asphalt-concrete mixture of the road surface. And the most effective method of disposal and neutralization of oil waste was chosen. In this article, it is proposed to develop an asphalt-concrete technology based on asphalt-resinous paraffin deposits. The issue of increasing the reserves of raw materials for the production of durable asphalt concrete and reducing the amount of oil-containing waste in the fields due to the sale of solid oil-containing waste will be considered. Based on the study, the composition of asphalt-resinous paraffin deposits was analyzed by IR spectroscopy. The infrared (IR) absorption spectrum was captured in the IR-Fourier spectrometer. The results of the study showed the suitability of asphalt-resinous paraffin deposits for use as organic binders to dense asphalt concrete of type «B» grade III for IV-V road climatic zones recommended for applying top layers of coating on roads of technical category IY.

It is necessary to carry out work to analyze the harmful factors of accidents during the production, operation and transportation of raw materials in oil and gas fields and assess their compliance with the requirements of the standards of the Republic of Kazakhstan. The main goal of labor protection is to create safe working conditions for employees, as well as to prevent personnel from illnesses. In this regard, it is necessary to have a system of accounting, analysis and assessment of the state of labor protection, as well as management of labor protection. This article proposes ways to quickly assess the state of health and safety at work by calculating a number of occupational risk indicators based on information available in the modules for assessing occupational safety by industrial risk indicators. The efficiency of using the OSH management systems software proposed by the authors is based on a specific task from four main modules "Employees", "Events", "Equipment", "Ecology" and a number of submodules. In addition, this work uses matrix methods for assessing risks in the "Probability or Consequences of an Event" coordinate system, "Elmeri" system, "Fine Kinney" method, "Risks". Modern expert methods are compared and presented under the title "Five stages of assessment"

Еліміздің аумағында мұнай-газ кешені пайдаланудың ірі инвестициялық жобаларын жүзеге асыру өнеркәсіптік, экологиялық қауіпсіздік пен еңбекті қорғауды басқарудың қазіргі заманғы әдіснамасына, нарықтық экономикасы бар елдерде сыналған әдістері мен құралдарын игеруге көшуге ықпал етеді. Дегенмен, қауіпсіздікті басқарудың нақты құралдарының апат пен жарақат көрсеткіштерімен байланысын талдау, сондай-ақ осы құралдардың тәуекелді бағалауға негізделген нұсқамалық тәсілден шынайы өндірістік тәсілге көшуді жүзеге асырудың жалпы жүйесіндегі орнын анықтау қажет. Өндірістік жарақаттануды талдау жарақаттануға әсер ететін ең маңызды екі фактор - бұл адами фактор және кәсіпорын басшыларының өнеркәсіптік қауіпсіздік және еңбекті қорғау (ӨҚ және ЕҚ) мәселелеріне назар аудармауы екенін көрсетеді. Мақалада Қазақстандағы өнеркәсіптік қауіпсіздік пен еңбекті қорғауды дамытудың негізгі үрдістеріне шолу келтірілген. Өндірістегі апаттар мен жазатайым оқиғалардың себептеріне талдау жасалды. Апаттар мен жазатайым оқиғалардың пайда болу теорияларын қарастыруға айтарлықтай орын беріледі, бұл өндірістегі ӨҚ және ЕҚ жағдайына әсер ететін әртүрлі факторларды ескеруге мүмкіндік береді. Сондай-ақ қорытынды бойынша зерттеу міндеттері қойылды.

This article suggests ways to quickly assess the state of labor protection and ecology by calculating a number of indicators of industrial risk based on the information available in the modules for assessing labor protection by indicators of industrial risk. The efficiency of using the software proposed by the authors for the occupational health and safety management system based on a specific task from the modules "Personnel", "Events", "Equipment" and "Ecology", consisting of four main modules, is proved. In addition, this paper compares the matrix methods of risk assessment in the coordinate system "probability of an event or consequences of an event" of prevention and assessment of occupational risks for employees used in domestic and foreign practice in the occupational safety management system.Work on identifying harmful factors of accidents during the extraction, use and transportation of raw materials at industrial enterprises and assessing compliance with the requirements of the standards of the Republic of Kazakhstan should be carried out continuously. The main goal of the labor protection service is to create safe working conditions for employees at industrial enterprises, as well as to prevent occupational diseases of employees. In this regard, a system of accounting, analysis and assessment of the state of labor protection, as well as labor safety management, should work.

This article discusses modern approaches to ensuring occupational safety and industrial safety at enterprises of the oil and gas industry. The main direction of the study is the use of the method of registration of hazardous situations as a tool for the formation of safe behavior of personnel and management of production risks. The formation of a security culture, the leadership role of managers, factors affecting the behavior of employees and the importance of information technologies in the process of security management were analyzed. In the course of the study, existing approaches to the detection and registration of dangerous situations, the possibility of preventing industrial injuries and accidents were considered. It is established that the information obtained as a result of the registration of hazardous situations makes it possible to assess the actual state of working conditions, identify hazardous factors in advance and make timely management decisions to eliminate them. In addition, the use of electronic information systems increases the efficiency of collecting, processing, storing and analyzing registered data. The proposed approach makes it possible to move from an instructive method to a risk-based management system in Occupational Safety Management and is considered as a practical tool aimed at preventing industrial injuries and accidents.
