摘要：
The development of coal resources in western China is a strategic task to ensure the supply of coal resources. The construction of mine with fewer people, safety, green, mechanization and intellectualization is an inevitable trend and important direction for the development of coal intellectualization at present stage. In this study, the status quo of technology and equipment for rock breaking used in the drift and vertical shaft of coal mines in China is summarized, and the common problems faced by different types of mechanical rock breaking for mine shafts are analyzed. For the Kekegai Coal Mine, its geological conditions is typical in western China with rich in water and weak in cementation. Accordingly, the development plan of Kekegai Coal Mine is determined to be a drift and shaft joint development plan. Considering the formation conditions, equipment performance, surrounding rock control and economic rationality, etc, the feasibility of using TBM for drift development and drilling rig for shaft development is studied and the concept of intelligent mine construction is proposed. The intelligent mine construction mode of mechanical rock breaking in the Kekegai Coal Mine is constructed. In the Kekegai mine, based on low coal formation rock strength and high disturbance sensitivity, the TBM technologies of high efficient rock breaking and surrounding rock control, continuous waste discharge, coordination of equipment forward movement and drift support have been developed. The technologies are applied and have realized a significant adjustment of TBM pose, excavation section of 40 m2, and a preliminary "detection-rock breaking-support-material transportation" integration continuous excavation technological system. The highest driving footage in a month reaches 523.8 m. It is the first time to use shaft drilling rig at weak cementation watery stratum in the western China. Therefore, the authors have put forward a method of "completion shaft with one drilling operation" for the shaft in whole rock strata, and formed a large shaft drilling rig and its accessory equipment system suitable for the drilling method in the coal measures strata in western China. The system consists of large diameter drill bit with whole section structure, stable drill pipe, large gantry crane and high efficient centralized control system for shaft drilling rig. The key technologies and intelligent monitoring problems such as the installation of large gantry crane for vertical drilling rig, and the intelligent control of tripping and efficient drilling of vertical drilling rig have been solved. A high-efficiency drilling ofφ8.5 m large diameter shaft in western water-rich and weakly cemented rock stratum has been realized, with the maximum one-day drilling depth of 10.8 m. © 2022, Editorial Office of Journal of China Coal Society.
