Research purposes:With speeding up the pace of China developing the overseas mining resources,the Chinese infrastructure companies took over many mine heavy - haul railway projects,with the axle load of more than 30 t and the traction quality of 20000 t or above. At present,there is no such project in China. This paper presents the overall design plan of the mine heavy - haul railway based on the study on the axile load,traction quality,number of the main track and maximum gradient according to the traffic demand and function orientation in order to break through the traditional design ideas in China.
Research conclusions:From the study it is concluded: (1) The plan of adopting the 37 t axile load and 3500 t traction quality is economic and reasonable.(2) The concept of strengthening the fundamental and weakening the trivial should be followed in matching facilities and the matching facilities should be simple,using China - made products.
