In this paper, the whole process of tower pole leaning in mined-out area is researched and the variation rule of the transmission line over the mined-out area is summarized through the case for tower pole leaning of the second line of Haihui-Jincheng. Then on this basis,preventive measures for tower in mined-out area are presented.
