Platinum group elements as geochemical indicators in the study of oil polygenesis
This study examines elements of the platinum group (PGE), primarily platinum and palladium, as geochemical indicators in the investigation of oil polygenesis. It has been found that, like other trace elements such as nickel, vanadium, and cobalt, platinum group elements and gold can occur in oil fields at both background levels and in elevated or even anomalously high concentrations. The objective of this research is to analyze PGE and trace elements as geochemical markers to identify the geological factors, including endogenous processes, responsible for these unusually high concentrations in oil. A comprehensive review of the literature on this subject was conducted, along with new data on the presence of precious metals in oils from Russia and globally. The study explores the geological mechanisms behind elevated PGE concentrations in oils, utilizing atomic absorption spectroscopy with atomization in the HGA-500 graphite furnace to measure PGE content. Previously, the tellurium co-deposition method (ISO 10478:1994) was used to isolate noble metals from associated elements. Possible geological origins of abnormally high concentrations of platinum metals in oils have been identified. These include endogenous factors such as the spatial proximity of oil fields to ultrabasic rock massifs, the effects of contact-metasomatic processes, and influences from mantle dynamics. Moreover, data concerning mantle elements can serve as indicators of the depth origins of certain hydrocarbon fluids, thus contributing to the study of oil polygenesis.

Study of thermodynamic processes of the Earth from the position of the genesis of hydrocarbons at great depths
In the context of significant depletion of traditional proven oil reserves in the Russian Federation and the inevitability of searching for new directions of study and expansion of the raw material base of hydrocarbon raw materials in hard-to-reach regions and on the Arctic shelf, a scientific search is underway for accumulations in complex geological conditions and in manifestations that differ significantly from traditional ones, which include the processes of oil and gas formation and preservation of oil and gas in low-permeability “shale” strata and in heterogeneous reservoirs at great and super-great depths. Within the oil and gas provinces of the world, drilling of a number of deep and super-deep wells has revealed deposits at great depths, established connections between hydrocarbon deposits and “traces” of hydrocarbon migration left in the core of deep wells, which has made it possible to significantly re-evaluate theoretical ideas on the issue of oil and gas formation conditions and the search for technologies aimed at solving applied problems. Modern geochemical, chromatographic, bituminological, coal petrographic and pyrolytic methods of studying oil and bitumoids extracted from the host rocks of deep well cores give a hope for identifying correlations in the oil-source system, revealing processes that determine the possibility of hydrocarbon formation and accumulation, and defining predictive criteria for oil and gas potential at great depths.

Indicator assessment of the reliability of mine ventilation and degassing systems functioning
- Authors:
- Nina O. Kaledina
- Valentina A. Malashkina
The gas emission control in the mines is operated by ventilation and degassing systems that ensure the aerological safety of the mines or minimize the aerological risks. The ventilation system of the mine and its individual sites includes a significant number of technical devices and equipment, and the air tubes are mainly mining workings, the condition of which determines the quality of the ventilation network (its capacity) and depends on a number of mining factors. Similarly, one of the most important elements of the degassing system, which includes its own chain of technological equipment, are wells, and in some cases, mining workings. Thus, mine ventilation and degassing systems cannot be attributed to purely technical systems, since they include mining elements characterized by high variability of the determining parameters. To assess their reliability, it is necessary to use various combined methods that include additional characteristics in relation to the mining component. At the same time, the reliability of technical devices that ensure the functioning of mine ventilation and degassing systems largely determines the efficiency (stability and reliability) of these systems and, consequently, affects the level of aerological risks. The described approach to assessing the reliability of ventilation and degassing systems of coal mines when analyzing aerological risks is based on the developed system of risk indicators for the methane factor and will allow determining the risk dynamics in automatic mode based on monitoring the parameters of the ventilation and degassing system state.

Application of automation systems for monitoring and energy efficiency accounting indicators of mining enterprises compressor facility operation
- Authors:
- A. V. Ugolnikov

The balance of electricity consumption a significant part is occupied by the production of compressed air at the mining enterprises. Many compressor stations of enterprises are equipped with automated parameter management systems that allow reliable, uninterrupted and safe operation of the compressor facilities. But the majority of automation systems at compressor stations do not perform the function of monitoring the energy efficiency indicators of the operation of a compressor station. The article discusses the issue of including compressed air flow sensors (flow meters) in an automated control system of a compressor station, which allows you to control the production of compressed air and the consumption of electrical energy for its production. Monitoring and recording of these parameters makes it possible, using microprocessor technology, to control one of the main indicators of energy efficiency – the specific energy consumption for producing one cubic meter of compressed air, determine how efficiently the compressor station works, and take appropriate measures to reduce specific energy consumption in time. . The use of additional functions of automated control and monitoring systems will allow the development and application of energy-saving measures aimed at improving the energy efficiency of the enterprise, which will lead to a reduction in the cost of finished products and increase their competitiveness

This paper examines problems related to forming a complex of indicators to assess innovation potential of an industrial enterprise, on the example of coal industry enterprises, and an integral indicator of innovation potential, used for comparative analysis of the state of affairs in the industry. Analysis of different approaches to defining the term «innovation potential» for industrial enterprises has been carried out; resource-based, resultative, integrative and capacitive approaches have been highlighted, the latter one based on assessment of enterprise capacities. A conclusion has been made regarding advantages of integrative approach. Research has been made on the role of industry in the fuel and power sector of China and dynamics of industry and enterprise development in Shanxi province. Basing on suggested approach a system of assessment principles has been formulated, taking into account specific features of coal industry enterprises. Complex of indicators to assess innovation potential has been developed using expert evaluation method. An expertise procedure is proposed to assess competence of experts; results obtained from the expertise are presented. Proposed complex of indicators includes 23 parameters combined into three groups. Testing of proposed complex of indicators has been carried out on the example of coal industry in Shanxi province (China). Application of all stated principles has been proved in the process of indicator selection, assessment and formulation of recommendations for subsequent innovation potential management of coal industry enterprises. Proposed approach to forming a complex of indicators of innovation potential for industry enterprises permits to link together the logic of innovation potential definition, formation of the system of its principles, selection of the indicators complex for assessment and subsequent innovation potential management of the enterprise.

Risk of injuries among coal mine workers and its hysteresis
- Authors:
- Yu. Parkhanski
The paper gives an overview of employment in coal mining, levels of extraction and injuries among the coal mine operators in Poland over a span of time from 1954 through to 2010. The injury indicators, such as the incidence rate, severity and the generalized loss index, have been assessed for a period of coal mining sector restructuring from 1993 to 2010. Diverging trends have been revealed, resulting in a need to extend the time span of the analysis. Analysis of records from 1954 to 2010 has shown a multiple cyclicity of trends of change in the values used to derive coefficients. The definition of the Injury Risk has been justified, along with a new way for its representation and its interpretation as a new method with account of the previous studies. Based on this method the injuries at the coal mines of Poland during a period of their restructuring have been investigated with analyzed database expansion to include records from 1954 to 2010.As a result a new dependency, namely the injury risk hysteresis, has been identified.
