Abstract: In order to meet the coal loading requirement at the collecting-transfer station, analysis is made of the structural design and working principle of both rapid constant-rate loading system and mobile loading system. Then the 2 different loading systems are compared from 3 aspects, i.e. technical feature, initial capital cost and surface layout, so as to define the most preferable system that can meet the design requirements. Analysis made in various aspects indicates that the use of mobile system can lead to reduction of investment, facilitation of further extension of Fenxirongxin special railway line, better control of consistency of coal loaded, and improvement of loading efficiency.
