Abstract: Against the backdrop of digitalization and intelligentization, the mining industry is gradually stepping into a new era of automation and informatization. This paper focuses on the Mine Harmony OS, an advanced intelligent mining platform, and addresses the core issues of low data processing efficiency and inaccurate fault diagnosis in traditional shearer monitoring systems. The research aims to design an efficient and intelligent shearer monitoring system by integrating advanced Mine Harmony OS technology, achieving real-time monitoring, precise fault warning, and remote intelligent control of coal mining operations, thereby significantly enhancing the safety and efficiency of coal mining. Firstly, the current status and challenges of shearer monitoring technology are analyzed, clarifying the urgent need for intelligent transformation. Subsequently, the overall architecture of the Mine Harmony OS is designed using a systems engineering approach, including a data acquisition layer, a transmission layer, a processing layer, and an application layer, with the functions and implementation methods of each layer detailed. In the data acquisition layer, various sensors monitor the working status of the shearer in real time; the transmission layer ensures real-time data transmission via high-speed networks; the processing layer conducts in-depth data analysis using advanced algorithms; and the application layer provides intuitive monitoring interfaces and decision support. The software aims to optimize the monitoring and control process of the shearer through intelligent means, improving mining safety and efficiency. The paper discusses the design, architecture, and functional characteristics of the intelligent shearer monitoring system software based on the minehub system and analyzes its practical production effects. The intelligent shearer monitoring system based on the Mine Harmony OS not only solves the deficiencies of existing monitoring technologies but also significantly enhances the level of intelligence in coal mining operations.
