The intelligentization of coal mines is the core technological support for the high-quality development of the coal industry, and also an important component of cultivating new quality productivity in the coal industry. The coal industry has promoted the rapid development of intelligent construction in coal mines through measures such as promoting mechanism guarantees, collaborative research and development of technology and equipment, and demonstration coal mine construction. The results of reducing personnel, increasing safety, and improving quality and efficiency are significant. This article summarizes and analyzes the development achievements of intelligent construction in China's coal mines and the problems existing in normalized operation and maintenance management. Based on a comprehensive summary of the construction and operation of the unmanned system in Baode Coal Mine, the existing problems are proposed. A management model based on human-machine material management and PDCA was proposed, and combined with the establishment and management practice of Baode Coal Mine's intelligent operation and maintenance management organization, the implementation effect of Baode Coal Mine in safety production, production efficiency, and achievement control was verified, providing an example and reference for the industry's intelligent operation and maintenance.
