“…However, we are aware of the presence of such equipment in a number of mining companies, and therefore, as an example in Figure 3, we have given the results of a study of one of the rock samples. The samples were studied on a STA 449 F3 Jupiter running the NETZSCH Proteus Termal Analysis software package [6,9,12]. The STA method allows you to evaluate such explosive and fire hazardous indicators as smoldering temperature, autoignition temperature, as well as assess the tendency of substances to spontaneous combustion, and much more.…”

“…At the same time, the impact on these factors is possible through the control (TP & PP) in normal (UH) and pre-emergency (UP) modes. Triggering conditions and events (IC&IE) correspond to the output of parameter values (TP&PP) beyond the boundaries of safe (normal) operating and required, in accordance with federal norms and rules by industry regulatory legal acts, ranges [7,9,10]. In this case, their transition to the region of unacceptable values will occur, as a result of which the requirements of the existing regulatory legal acts will be violated [7].…”

The relevance of the work is due to the introduction of new high-intensity mining technologies underground, the conduct of mining operations at ever greater depths of coal and ore, changes in the explosive properties of the extracted raw materials, as well as incidents and accidents of varying severity occurring at mining facilities. There is an opinion that one of the causes of accidents and emergencies in mines is the inability to take into account both the features of the manifestation of the properties of the rock mass and the change in the explosive properties of minerals. The problem of applying a risk-oriented approach, namely a comprehensive assessment of the risk of accidents, in this case fires and/or explosions, has not been resolved. The applied risk calculation methods are diverse, as a rule, the accuracy of the results is low, and none of them allows taking into account all the identifiable hazards that lead to the occurrence of endogenous and exogenous fires, as well as explosions of hybrid mixtures in the space of mine workings. This article attempts to study in detail the prerequisites for applying a risk-based approach to solving this problem. Theoretical approaches and risk assessment in mines and mines are considered and methods are given that allow in express mode to obtain up-to-date information on the explosive and fire hazardous properties of the extracted raw materials.

“…One of the possible aerological ventilation schemes for double-way distilling tunnels, with the help of which forced circulation of air masses in the tunnel space can be ensured, is a heat and mass transfer scheme using a technical (specialized) rigid ventilation structure located at the tunnel arch (false ceiling) [17,18,19]. A similar solution has already found its application, for example, in ventilation systems for road tunnels.…”

The article discusses the issues of operating existing metro lines with double-track tunnels. Significant differences between average annual, average monthly and extreme values of outdoor air temperature affecting the thermodynamic and thermophysical parameters of the mine atmosphere of subway tunnels, both in Russia and abroad, are analyzed. The results of a comprehensive analysis of the conditions that determine the temperature regime of the lines of double-track tunnels are presented. Air recirculation in the tunnels has been determined considering climatic conditions. Engineering and technical calculations have been carried out in metro tunnels when the seasonal periods of their operation change. Each of these periods is characterized by its own temperature, for example, for the winter period these are: average winter temperatures, temperatures of the coldest month, the coldest five-day period. The obtained results of the research work will make it possible to select the amount of air for each specific variant of the year, which will ensure, during the operation of this kind of metro lines, the standard thermodynamic parameters of the air environment, both in underground stations and in metro tunnels, and possibly lead to a positive economic effect.

“…It is impossible to foresee everything. Therefore, special attention is paid precisely to the development of project documentation [14,15]. The main legal regulations of the Russian Federation, which primarily guide specialists in the field of design and conduct of mining operations, are the Russian Federation Law "On Subsoil", "Requirements for the structure and execution of project documentation for the development of deposits of solid minerals, the abandonment and conservation of mine workings and the primary processing of mineral raw materials "and other normative and legal acts of the Ministry of Natural Resources and Ecology of the Russian Federation, as well as "Requirements for the preparation, content and execution of plans and schemes for the development of mining operations and application forms for approval of plans and (or) schemes for the development of mining operations" NLA of the Federal Service for Environmental, Technological and nuclear supervision (Rostekhnadzor) (for the translator -The Federal Service for Environmental, Technological and Nuclear Supervision (Rostekhnadzor; Russian)) (similar documents are available in other countries).…”

The article presents a pioneering integrated approach to assessing compliance with environmental, fire, industrial safety, and labor protection requirements in open-pit mining operations. The study was conducted at two existing open-pit mining facilities located in the Trans-Baikal Territory of the Russian Federation, analyzing the causes of injuries, statistical data, and comparing the mining technologies used. The key findings emphasize that the efficiency of deposit development and the safety of mining operations are heavily dependent on the quality of the technical design. The article also discusses software systems used for the design of mining facilities, which enable monitoring of the safety and labor protection aspects during quarry operation. The results of the comparative analysis are expected to be of interest to both quarry design specialists and the engineering and technical personnel of existing open-pit mining facilities. This integrated approach represents a significant advancement in the field, providing a comprehensive framework for enhancing safety and operational efficiency in the mining industry.
