    Abstract: Based on the demand of intelligent development in coal mine construction stage, the definition and scientif⁃ ic connotation of “intelligent shaft construction, intelligent mine construction” are put forward, and the important role of intelligent shaft construction in coal mine intelligent construction is expounded. The problems of shaft con-struction in western China are analyzed, such as complex geological conditions, weak basic theory research, lagged research and development of intelligent shaft construction equipment and difficulty in engineering technological breakthroughs. The overall structure of an intelligent shaft construction system is constructed, which is composed of a perception layer, transmission layer, edge layer, platform layer, and execution and application layer. The intelligent shaft con⁃ struction cooperative control system is developed, which is composed of inclined shaft driving control, vertical shaft drilling control, and comprehensive support system. Through the base theory research, process design, intelligent equipment development, control system development, field engineering demonstration of research ideas, this paper summarizes the intelligent construction of coal mine shaft, and solves the difficult technical problems in mine shaft construction including the low efficiency of rock fragmentation in whole section shaft excavation , the dif⁃ ficulty in excavating the strata with complex formation, the prevention and control of groundwater, and shaft stability and supporting. Through the practice of intelligent shaft construction project in the Kekegai Coal Mine of Yanchang Petroleum Group, the open⁃type full⁃section intelligent driving method of inclined shaft is developed, and the integrat⁃ ed operation of “exploration, excavation, support, anchoring and transportation” is realized. It has formed the intelli⁃ gent drilling method of “one drilling and completion” in the shaft, realized the essential safe operation of “under⁃ ground unmanned construction” in the shaft drilling, created the engineering and technology demonstration of intelli⁃ gent shaft construction in the industry, and formed the “Yanchang mode” of intelligent shaft construction in the coal industry. Finally, combining with the intelligent development trend of coal mines, the paper puts forward the princi⁃ ples and objectives, current work and development direction that the coal industry should follow in shaft construction, and call on the whole industry to focus on intelligent shaft construction technology and promote the development of coal mine construction to the safe, efficient, green and intelligent direction.
