Research and Application of In-situ Mobile Intelligent Dry Sorting Technology for Shengli No.1 Open-pit Mine
Abstract：To solve the problem of in-situ sorting and inconvenient mobility of the underground sorting system under extreme cold conditions in Shengli No.1 Open-pit Mine, this study investigated the stable operation technology of intelligent dry sorting machines under extreme cold conditions, the mobile methods of the underground intelligent dry sorting system, and the technology to improve the processing capacity of the dry sorting machine. By developing an internal thermal circulation system and an adaptive temperature control system within the container, a device protection plan under extreme cold environments was established; by comparing various mobile methods, a combined mobile scheme was determined; by optimizing coal gangue identification algorithms and equipment structure, an efficient processing system was constructed. The results show that the equipment can operate stably under extreme cold conditions, the underground mobility is convenient, the conveyor belt speed of the dry sorting machine reaches 3.2-3.6 m/s, and the accuracy rate of coal gangue identification is ≥95%, which improves the level of coal mine intelligence and resource utilization.
