Abstract
The article presents a study and analysis of the causes of deformation of the slopes and sides of the quarry indicates that the magnitude and nature of the deformation processes depend on the height of the ledge, the angle of slope of the slopes, the physical and mechanical properties, the lithological and structural features of the instrument array and the geodynamic activity of the fault zones. The influence of the deformation zones of the sides of the quarry on the transport of rock masses is justified. The zone of deformed masses of the ore deposit, which affect the movement of the rock mass, is studied. Each process performed in open pit mining is linked to another workflow. Without ensuring the safety of mining operations and performing the tasks set is impossible. Transportation of rock masses in the lower horizons of a deep quarry is one of the main tasks of the industry. At the same time, the removal of deformation and landslides in the area where the transport berm is being constructed for draining and continuous transportation is the main goal of the quarry. The stability of the transport berm depends directly on the stability of the side of the quarry. It is determined that the choice of a single-lane or twolane transport berm constructed for heavy-duty quarry dump trucks depends on the condition of the side of the quarry.
Highlights
Ensuring the stability of the sides of quarries is a very urgent problem [1, 2]
The main transport berms are located on the North and South sides of the quarry
It is necessary to take into account the degree and volume of deformation on the sides of the quarry where the transport berm passes
Summary
Ensuring the stability of the sides of quarries is a very urgent problem [1, 2]. The issues of stability are solved in the conditions of the unique diversity of mining and geological conditions in a very strict economic framework when determining both the maximum depth of open-pit mining and the slope angles of the sides on the limit contour. Among them are the following: - increase in economically feasible depths of open works; - the interdependence of slope stability with the development system and the mining regime; - the need to change the parameters and configuration of slopes during the operation of quarries; - determining influence of technological factors; - maintaining the slopes of the sides of the quarry in a stable state; - creation of normal working conditions for mining and transport equipment. This example shows that the transfer of research results is possible when taking into account geological features, and all the factors that determine the stability of the sides of quarries. Depending on the purpose of the slope section of the quarry side and the time of its existence, there are five groups of slopes: - slopes of the opening workings; - permanent boards near protected objects; - permanent boards that do not contain transport communications; - temporary-permanent boards; - slopes of working ledges
