On basis of the design parameters and the engineering geology of Taihangshan tunnel, comprehensive comparison and contrast are made for the railbound transportation system and trackless transportation system for the construction of the main tunnel of working lot of No. 7 inclined shaft of Taihangshan tunnel in terms of construction advance rate, full use of the equipment resources and the transportation safety factor. The analysis result indicates that the trackless transportation system has great advantages and can dramatically improve the comprehensive efficiency of the works. The paper can provide reference for similar works in the future.
