Application status and development thinking of intelligent mining technology and equipment in coal mines in China

The intelligent technology of coal mines is the core technical support for the high-quality development of the coal industry, and the intelligent mining technology and coal machine equipment of coal mines are the key to the intelligent construction of coal mines. On the basis of a detailed analysis of the current situation of the primary stage of intelligent construction in China’s coal mines and the constraints on the development of intelligent technology and equipment in coal mines, this article analyzes the advantages and disadvantages of intelligent mining technologies such as adaptive planning and cutting control of coal mining machines, intelligent comprehensive control of scraper conveying equipment, hydraulic support electro-hydraulic control, geological guarantee of transparent working faces, straightness monitoring of working faces, precise positioning and active protection of working face personnel, and AI recognition monitoring of working faces.The analysis results show that the intelligent construction of coal mines has brought unprecedented opportunities for the development and upgrading of the high-end coal mining equipment industry. The deep integration of modern information technology and high-end coal mining equipment has greatly innovated China’s coal production mode. However, the bottleneck of intelligent mining technology still restricts its high-quality development, and there is still a significant gap between achieving “less manpower, unmanned” mining in coal mines. As a collaborative system engineering of “human, machine, environment, and management”, the intelligent construction of coal mines is proposed by the author to break the traditional concept of “individual combat” and adhere to the construction concept of “organic intelligent collaboration” to solve the current technological bottleneck. For example, strengthening the transformation of high-end coal mining equipment to new digital intelligence, improving the three-level vertical safety control technology of ground edge end, transforming the planning perception and guidance device from superposition expansion to organic integration, establishing a digital management system for the entire life cycle of equipment, and guiding the transformation of single machine intelligence to group collaborative intelligence are suggested to promote the high-quality development of coal mining equipment technology in China's coal mines.
