Evaluation of stability of sides of quarries and dumps on the basis of a risk-oriented approach

Abstract

purpose. The current conditions for open pit mining lead to a number of problems that arise both for domestic and foreign enterprises of the mining complex. In this regard, the aim of the article is to assess the stability of the sides of quarries and dumps based on a riskbased approach. Methodology. The main research method is a method for analyzing the probability of certain risks, and the method is based on the use of a riskbased approach to assess the risk of collapse in quarries. This approach allows us to assess the stability of the quarry sides and dumps, as well as to select a set of measures to ensure the stability of the array. findings. The authors analyzed the existing shortcomings in the regulatory documents related to ensuring the sustainability of quarry sides and dumps. It was found that at the present stage they are not able to effectively ensure the development of internal local documents of enterprises in the field of the occurrence of damage associated with the collapse of rock masses. The data obtained from the construction of the fault tree showed that a comprehensive solution to the problem is needed by attracting a riskbased approach and selecting measures to strengthen the quarry sides and dumps. originality. For the first time, the authors applied a preventive riskbased approach to solve the problems with the stability of quarry sides and dumps in a real mountain facility. practical value. The results can be used to reduce the level of occupational injuries by reducing or eliminating emergencies associated with caving and landslide phenomena during the operation of an existing quarry.
