Abstract
The object of the study is the Far West quarry of Zhairemsky Mining and Processing Plant JSC. During the research work, the physical and mechanical properties of rocks at the Zhairem deposit were studied, an analysis of the correspondence between the actual and design parameters of the quarry was carried out, and field studies of rockfalls were carried out taking into account geotechnical domains. Due to an increase in the depth of development and a decrease in the width of the upper horizons of the Far West quarry, it is necessary to carry out an assessment of the risks of rockfalls and issue recommendations to reduce these risks. To achieve this goal, the following tasks have been identified: analyze previously performed studies; analyze the existing condition of the quarry sides; comparison of actual and design parameters of benches; division of the edge massif into geotechnical domains based on the results of structural zoning; field studies of rockfalls to determine the coefficient of normal and tangential recovery; analyze rockfalls in RockFall software; development of recommendations to reduce the risk of rockfalls.
