Abstract: The effective application of electrical automation technology in coal mine engineering has become a crucial approach to maintaining mining safety, achieving efficient production, and ensuring stable operation of electromechanical equipment. This paper explores how the implementation of electrical automation technology in coal mine engineering planning and management can facilitate high-precision monitoring, flexible control, and low-energy operation. It emphasizes that mining enterprises must implement key technologies such as mechanized coal mining operations, automated transportation monitoring systems, and automated safety detection and control mechanisms. These measures will enable coal mine engineering to achieve satisfactory operational outcomes through the support of electrical automation.
