With the rapid growth in coal demands driven by economic development, the applications scenarios of long-distance, high-power mining operations in underground coal mines have gradually expanded. This paper analyzes the mechanisms behind voltage fluctuation hazards and the status quo of existing voltage regulation technologies in coal mines, focusing on voltage regulation technology for long-distance power supply in tunneling faces based on on-load voltage regulation. A voltage regulation device specifically designed for long-distance power supply was implemented in the Wanli Coal Mine’s tunneling faces. The evaluation indicated that all indicators met the design requirements, thereby validating the effectiveness of the device and the applicability of the research outcomes. This work provides an effective solution to address voltage fluctuations in the long-distance power supply of underground coal mines.
