Study the Performance of Coal Gangue Filling in the Road Embankment

Coal gangue is a byproduct of mining process, filling the gangue in the road embankment can reduce the pollution caused by the gangue accumulation. Because the formation and type of rock is different, the performance of gangue is different. In this paper, the main types of gangue of Handan & Xingtai coal mining area was taken laboratory test, the mechanical properties and chemical properties of different gangues were compared to determine the feasibility of gangue filling in the road embankment, and the performance law of coal gangue.
