Abstract:

Purpose. A comprehensive analysis of the deformation processes occurring in the quarries of the Republic of Uzbekistan, such as Muruntau and Kalmakyr, with the aim of identifying the key factors influencing the stability of rock masses. Development of practical recommendations and effective measures to ensure the long-term stability of quarry slopes, prevent collapses, and minimize risks to worker safety and the environment.

Methodology. The study involves a comprehensive analysis of geological, tectonic, and climatic factors affecting the stability of quarries. For this, data from long-term monitoring (1979–2024) is used, allowing the identification of trends and patterns in deformation processes. Additionally, the method of modeling the stress-deformed state of rock masses is applied to assess risks and develop predictive models of quarry behavior under various conditions.

Findings:

-     the main types of deformations have been identified: collapses (82 %), landslides (18 %);

-     key destabilizing factors have been identified: tectonic faults, fracturing, drilling and blasting operations, and geodynamic activity;

-     critical slope angles have been determined (for the northern slope of Muruntau – 38°);

-     measures to improve stability have been proposed: geomechanical modeling, dynamic monitoring, optimization of drilling and blasting operations, and rock reinforcement.

Originality. The interrelation between tectonic disturbances and the mechanisms of slope failure has been identified. Parameters of residual deformations after blasting operations have been determined. Recommendations have been developed for adjusting slope angles depending on lithology and fracturing.

Practical value. The developed methods of monitoring and geomechanical modeling can be successfully integrated into quarry stability control systems, providing more accurate diagnostics of rock mass conditions. Optimizing drilling and blasting operation parameters, such as drilling grid, type and amount of explosives used, as well as the sequence and timing of detonations, will significantly reduce the risk of damage and increase the efficiency of mining operations. The use of innovative technologies, such as intelligent fiber-optic sensors, ensures continuous real-time monitoring of the rock mass condition, facilitating prompt responses to changes and preventing emergency situations.

Keywords: deformation processes, slope stability, landslides, collapses, geomechanical modeling, monitoring systems, geodynamic activity
