269 equipment is facing the requirements of extreme working conditions such as long distance, large lifting height, high production capacity and large driving power. Its development process faces technical problems such as complex dynamic characteristics of the whole machine (Wang J.Q., 2024; Yang Z.G., 2025), insufficient reliability of key components (Zhao L., 2023), low level of intelligent operation and maintenance (Xi C.G., 2023), and there is no mature application case at home and abroad for reference. The intelligent demonstration mine with an annual output of 25Mt is under construction in Kekegai coal mine of Yanchang Petroleum, Shaanxi Province. Its transportation distance is longer than 5000m and the lifting height is greater than 500m, which puts forward extreme requirements for transportation equipment. Based on this, this paper conducts research on the key technologies of the intelligent and efficient belt conveyor for super power main inclined shaft, focusing on breaking through the problems of the whole machine dynamics modeling, key components optimization, digital twin intelligent operation and maintenance system construction, and conducting industrial test verification, aiming to break through technical bottleneck and fill the gap in China. DYNAMICS ANALYSIS AND COORDINATED CONTROL OF THE ENTIRE SYSTEM Configuration and Optimization of Distributed Drive Systems Aiming at the problem of dynamic tension control and multi driving point power collaborative distribution, in the process of conveyor belt starting and braking, under the condition of long distance and large lifting height, combined with the characteristics of large lifting height and long distance of main inclined shaft roadway in Kekegai coal mine, the distributed driving technology is adopted from the aspects of equipment safety and reliability, research and development cost, roadway support construction and operation and maintenance convenience. Table 1 compares the key parameters of head centralized drive and distributed drive, as well as their advantages and disadvantages.
