Research of the deterioration mechanism and the prevention techniques of the main structure of conveyor gallery in colliery industrial environment


In the colliery industrial environment, the materials of reinforced structure suffer relatively serious aging. The cracking and deterioration of concrete and the corrosion of steel member lead to the degeneration of structural performance and the decline of structural reliability. In this paper, the experiment is combined with the test engineering instances of colliery industrial ground environment and the main reinforced structure of conveyor gallery at Jiahe Colliery, Chacheng Colliery, Woniushan Colliery and Zhangji Colliery attached to Xuzhou mining group co., Ltd in China. During the experiment, colliery industrial environment is analyzed qualitatively and quantitatively; and at the same time, damage degradation characteristics and security design check method of reinforced structure of conveyor gallery are studied. Then, deterioration mechanism of reinforced concrete conveyor gallery under the coupling action in the industrial environment is investigated from the aspects of material & components & structure. Finally the corresponding prevention and control technology are proposed, which provide sound proof for the reliability of reinforced concrete conveyor gallery.
