ABSTRACT
In underground construction, there is a high risk of emergency situations and accidents that can lead to death of people. Therefore, the article has developed methodology for calculating risks in underground construction, which provides for the allocation of individual components of the total damage (consequences) from risks and the determination of the price of each component from various causes. The proposed approach allows targeted implementation of risk mitigation measures. For example, protective actions are applicable to a specific, most significant consequence, while not addressing causes and events whose risk cost, except for the mitigated consequence, remains acceptable or negligible. The above methodology will later help to create a risk register for typical facilities, which will make it possible to determine the most appropriate protective measures necessary for the construction and operation of underground structures.
