Introduction. This study focuses on the development and modeling of an efficient automatic control system and electric drive for mine ventilation installations based on a screw compressor. The harsh operating conditions of underground mining – characterized by high dust levels, variable loads, vibrations, and strict safety requirements – demand reliable and energy-efficient ventilation systems. Conventional solutions, such as direct start asynchronous drives or non-optimized compressors, often result in high energy consumption, increased mechanical stress, and reduced service life. The integration of frequency-controlled drives with advanced control algorithms offers a promising approach to improve system performance, reduce costs, and ensure stable operation in mining environments. Methods. The research methodology included the construction of a mathematical model of a high-power asynchronous motor with vector control, simulation of dynamic processes in MATLAB/Simulink, and evaluation of transition characteristics under different load conditions. Special attention was paid to the implementation of a soft-start intensity regulator and anti-surge control algorithms. The screw compressor and drive interaction was analyzed using differential equations of electromagnetic processes and gas compression parameters. Performance indicators such as torque, rotational speed, outlet pressure, efficiency, and energy consumption were assessed in both steady-state and transient modes. Results. The modeling results demonstrated that the use of a frequency-regulated drive reduced peak electromagnetic torque from 18,000 to 13,500 N·m and shortened acceleration time from 70 to 48 seconds compared to direct start. The output pressure of 4.35–4.40 MPa was achieved with stable dynamics, while peak currents decreased by 18%, mitigating thermal overloads. The proposed system improved compressor efficiency to 88–89% in nominal modes, provided up to 17% energy savings, and stabilized thermal and pressure regimes. Anti-surge regulation increased the safety margin by 12–14%, completely preventing transitions into unstable operating modes. Conclusions. The study confirms that integrating a screw compressor with a variable-frequency asynchronous drive and an automatic control system significantly enhances the reliability and energy efficiency of mine ventilation equipment. The developed approach reduces energy consumption, extends service life, and improves operational stability compared to traditional solutions. The proposed methodology can be applied both in the modernization of existing ventilation systems and in the design of new installations, offering substantial technical and economic benefits for mining enterprises.
