This paper analyzes the development and current situation of intelligent mining technology at home and abroad, summarizes the development history, important technical achievements, policy guidance and development direction of intelligent mining at home and abroad, and summarizes the four practice stages of intelligent mining in China. The United States, Australia, Germany and other countries have taken the lead in the development of coal science and technology. They have made remarkable achievements in the key technologies of longwall mining, and established a new production mode of advanced intelligent continuous mining based on automation, informatization and digitalization. Compared with foreign countries, the Longwall mining technology of mine engineering in China has experienced the development process of digesting and absorbing foreign technology and equipment, and innovating and practicing mining technology and equipment according to the coal seam storage conditions in China. In the past 10 years, the intellectualization of longwall mining in China has achieved rapid development around the intellectualization of mining equipment and mining process, and has achieved the lead from following and running together. The development practice of intelligent mining in China has gone through four periods: visual remote intervention, automatic straightening of longwall mining, intelligent decision-making control, roboticized and transparent mining. The technologies of intelligent decision-making control, roboticized and transparent mining are not mature enough. China's coal intelligent mining technology is at the primary stage, and the system of intelligent perception, intelligent decision-making and control technology is not perfect. It is urgent to achieve subversive innovation in intelligent control technologies such as accurate detection, all-round multi-dimensional perception, multi system integration, analysis and prediction, independent decision-making, and collaborative control.
