Abstract: The article discusses the current situation, technical characteristics, and technological trends of intelligent coal-fired power technology, as well as the impact of relevant domestic policies on its development direction. Among them, metrology and procurement have achieved full process automation and unmanned operation. The focus was on analyzing the current status of unmanned sampling, automatic sample preparation, and automatic laboratory technology, as well as the integrated control of sampling and preparation. Analyzed the current status of intelligent control technology, including digital coal yards, coal blending and burning, and inspection robots. At the same time, the development trend of coal intelligent technology has been proposed. The systematization of mechanical intelligent sampling and preparation equipment is the future development trend of coal detection. The relevant standards for coal detection have played an important role in regulating China’s coal trade market and guiding enterprises to use coal reasonably. Coal detection equipment is developing towards automation, efficiency, intelligence, and high-end. The application of standard materials has promoted the progress of coal detection technology.
