Abstract: In order to realize intelligent production control and management of coal mine step by step, through a comprehensive assessment of the operation status of compressed air system in Taiping Coal Mine, the technical renovation of its critical control segment was carried out, including reform the main compressive equipment of coal mine with low cost, update the software control system and add sensor monitoring module, etc. The precise control technology of constant pressure air supply was introduced to ensure the stable air supply of the compressor unit. The result showed that after the technical renovation, the compressed air system of coal mine has realized the real-time monitoring and warning, as well as intelligent system management for the downhole equipment, the quality and stability of air supply are improved, good economic and security benefits are obtained.
