Abstract:
The intelligent construction of coal mines is in line with technological revolution and industrial transformation, and the deep integration and application of new generation information technology and coal development and utilization technology is an inevitable choice for the upgrading, transformation, and high-quality development of the coal industry.Since Huangling Mining established China’s first ground remote intelligent coal mining working face in 2014, intelligent mining technologies for thin coal seams, medium thick coal seams, thick coal seam comprehensive mining, and top coal caving have gradually been developed. These technologies have been promoted and applied by Huangling Mining to major production mining areas nationwide, and a theoretical, technical, equipment, and standard system for intelligent coal mining has been established; The overall breakthrough of intelligent mining technology in coal mines has driven the development of intelligent coal mines in China. Since the National Development and Reform Commission and eight other ministries issued the “Guiding Opinions on Accelerating the Development of Intelligent Coal Mines” in 2020, China’s coal industry has entered the era of intelligent coal mines driven by intelligent mining and breakthroughs in other core technologies, and has formed coal mine intelligent technologies including information infrastructure, geological support, mining, excavation, transportation, ventilation and air pressure, power supply and drainage, safety monitoring and control, operation and management, comprehensive resource utilization, etc., which has greatly improved the level of coal development technology in China and promoted the development of coal mine construction towards safe, efficient, green and intelligent direction.With the development of intelligent construction in coal mines, the research and development of mine construction technology and equipment lags behind, which is not matched or coordinated with the development of intelligent coal mines, seriously restricting the safe and efficient development of high-quality coal resources in China. Based on the intelligent development needs of the coal mine construction stage, the definition and scientific connotation of “intelligent well construction, intelligent mine construction” was proposed, and analyzed the problems faced by well construction, such as weak basic theoretical research, lagging research and development of intelligent well construction equipment, and difficult breakthroughs in engineering technology; We have constructed the overall architecture of an intelligent well construction system, developed an intelligent well construction technology equipment system based on the inclined shaft open full section tunneling machine and vertical shaft drilling rig “one drilling completion”, and built the first intelligent well construction technology demonstration project in China. The development practice of the past ten years has shown that the intelligent construction of coal mines in China has driven the overall technological leap and high-quality development of the coal mining industry.
