摘要
This paper appraises the influence of mining of coalfield layout area to the foundation stability of the transmission towers. Based on the locally collected data, it used the FLAC3D numerical method. The mining simulation of the coal seam 3# under the N177 tower of the 1 000 kV UHV transmission line is presented. After the coal seam 3# has been conducted, the numerical simulation of coal seam 9# is established. The results are as follows: The mining of the coal seam 9# can bring influence on the stability of the transmission tower foundation. The most subsidence of the ground is 1.15 m and the most inclination of the transmission tower foundation along the power line is 5.7‰.
