Abstract:
Application of TBM in coal mine excavation is increasing, and the transportation of construction materials within the tunnel significantly impacts efficiency, safety, and quality of TBM. To address the challenges of materials transportation for deep vertical shaft TBM operations, a comprehensive analysis was conducted. Block design technology was applied for targeted design of large TBM components like the cutter head, and auxiliary transportation tools were developed to overcome size issues for underground transportation of large TBM parts. A full-process design was implemented for inclined shaft material transportation, solving difficulties associated with long-distance and steep slope material lifting. The efficiency of TBM material transportation was thoroughly analyzed, and the recommendations for on-site material scheduling were proposed. By examining issues from the perspectives of large equipment transportation, long-distance inclined transportation, and efficiency improvements, new design solutions were proposed, ensuring successful material transportation for ultra-deep vertical shaft TBM operations, maintaining TBM efficiency.
