Preventing losses and reducing possible hazards is the most urgent and important task in mining. Implementation of this task occurs throughout the entire life cycle of mining production, starting from the development of project documentation and ending with the stage of modernization or liquidation of spent mining production. For mining production as a dangerous production facility [1], it is necessary to develop a modern methodology for risk assessment, accident identification for subsequent analysis, development and implementation of measures to reduce it in the production process. To solve this problem, the most promising method is the analysis of technogenic risk, which must be developed in relation to mining facilities. methods and means of mining. Mineral resources are part of the natural environment, the impact on the natural environment is provided by technical equipment and technological processes necessary for the extraction of minerals [2]. For risk analysis, mining production must be represented as a complex system consisting of the following subsystems: natural; technological; technical; organizational, social, psychological, etc. This study examines natural and technological risks. For each subsystem, factors affecting the probability of accidents and the amount of expected damage are analyzed, and then measures to reduce the risk are proposed. Risk assessment should be part of a comprehensive approach to business management. A systematic and comprehensive approach to risk assessment will allow you to take possible measures to eliminate (reduce) the risk. A systematic approach to risk assessment helps to prevent losses and improve safety in the mining industry by taking better account of possible situations, identifying those responsible for the risk, prioritizing the urgency of execution, and evaluating the risk justification scale.

Abstract The world is experiencing a rapid loss in the biodiversity of pollinator insects. Habitat segmentation caused by infrastructures is one of the contributing factors. To improve the habitat connectivity of pollinator insects, it is proposed in this study to build green corridors for pollinators over linear infrastructures such as highways. In the context of suburban areas of a large city, this study examines differences in air parameters between natural environments and a roadside environment based on monitored and estimated data. Influences of different green corridor designs on floral scent dispersion are also investigated using computational fluid dynamics (CFD) modeling and simulation. It is found that, if flower plants are installed on highway overpasses, the floral scents would be better preserved as compared with those in a natural environment due to the lower concentration of oxidative radicals in the air over highways. The stronger floral scents and their wider dispersion may help attract pollinators. Conversely, highway air contains a variety of volatine organic components (VOCs) that are likely traced to highway operations and pavements. Hence, the overall profile of VOCs in a highway environment differs from that in a natural environment. Results from CFD modeling and simulation suggest that the use of green corridors planted with flowers on the highway overpass can greatly improve the connectivity of floral scents. Hence, with proper engineering design and right combination of plant species, green corridors built on highway overpasses have the potential to facilitate pollinators to cross the road, thereby improving their habitat connectivity and resilience against declining biodiversity.
