Abstract: China's coal industry is undergoing structural changes. The output of raw coal has reached a new high. The level of clean and efficient utilization of coal has been continuously enhanced, and the rate of raw coal washing has been increasing year by year. As one of the important processes in coal washing, the control accuracy of the slurry concentration and dosing process has a decisive influence on sedimentation effect, reagent consumption and operating costs. The quality of China's raw coal is complex and changeable. In recent years, with the change of coal mining methods, the amount of primary and secondary coal slimes has increased significantly, and the difficulty of slurry treatment and the stability of treatment effects are quite challenging. The national and local governments have successively issued multiple policies and guiding documents, providing clear guidance for the scientific, standardized, and orderly development of intelligent construction of coal preparation plants. Efforts are encouraged to establish standard systems, formulate standards for the construction of intelligent coal mine as well as coal preparation plants. For this purpose, the basic requirements for the intelligent coal slurry dosing system of coal preparation plants are proposed. The system architecture is constructed with detailed regulations and technical conditions that each level of the system needs to meet, to provide guidance for the construction and transformation of the coal slurry dosing system and even the coal preparation industry. The constructed intelligent coal slurry dosing system includes the equipment layer, intelligent management layer and intelligent decision-making layer. Among them, the equipment layer is the bottom-level support, consisting of monitoring units for feed properties, clear water layer, underflow concentration and dosing amount. The control execution units were composed of software, computers and automatic control devices, as well as intelligent auxiliary equipment such as workstations and mobile terminals, providing data support for the intelligent management layer and intelligent decision-making layer. The intelligent management layer integrates and processes the monitoring information fed back by the equipment layer, to provide analysis basis for the intelligent decision-making layer. The intelligent decision-making layer, based on the data analysis and calculation of the former two, realizes autonomous decision-making in the dosing process. In the future, through the integration with more advanced technologies, continuous promotion of technological upgrading and optimization and innovation, the intelligent coal slurry dosing system will achieve greater breakthroughs in improving processing efficiency, reducing chemical agent consumption, stabilizing effluent water quality and reducing manual intervention.
