Safety improvement in open-pit mines with challenging mining conditions through upgrading avalanche prevention measures

One of the most common problems mining companies face in developing open-cut deposits in complicated geological and climatic conditions is avalanches during the spring-winter work period. This phenomenon is accompanied by a rapid displacement of snow masses, which can lead to catastrophic consequences. In this regard, the article aims to develop a modernized set of measures for avalanche protection. Prevention of avalanches of catastrophic scale, leading to blockages, road closures, and accidents, and the introduction of measures to reduce accidents and injuries in quarries and dumps, is a time-consuming task that requires serious approaches to its solution. The main research method is analyzing the applied anti-avalanche measures for active impact on snow cover and considering the possibility of using safer methods for active impact on avalanches at a particular mining enterprise. This approach allows for the evaluation of the advantages and disadvantages of the avalanche measures used and for choosing a set of measures to ensure more effective avalanche protection. The authors analyzed the existing shortcomings in the regulatory documents related to the provision of avalanche protection and anti-avalanche measures. It was found that they are not able to effectively ensure the development of internal local documents of enterprises in the field of anti-avalanche measures at the present stage. The resulting study showed that a comprehensive solution to the problem is needed through the introduction of several anti-avalanche devices to reduce the likelihood of avalanches of catastrophic scale. For the first time, the authors attempted to justify the possibility of using a modernized set of measures for the preliminary descent of snow avalanches to solve the problem of avalanche protection in the conditions of a real mountain object. The results obtained can be used to reduce the level of occupational injuries by reducing or eliminating accidents associated with unforeseen avalanches during the operation of an existing quarry.
