Abstract

As China’s power state grid continues to expand, transmission line towers are significantly affected by the threat of mining activities. In order to deeply understand the effect of ground deformation induced by coal mine gouging collapse on the vulnerability of transmission towers, the transmission line towers within the coal mine area of Liupanshui City and Bijie City in Guizhou Province in southwestern China were studied as the research objects, and the transmission line towers around Hongxing Coal Mine were taken as an example, and the vertical settlement amount at the tower was obtained using SBAS-InSAR technology. Through on-site investigation, the damage classification level of the transmission tower in the coal mine gouging area was constructed. By introducing a log-normal distribution function, a nonlinear functional relationship between the accumulated vertical settlement amount of the tower and the tower damage probability is established, and the equivalent damage probability of the tower is calculated. The vulnerability of the tower is divided into five levels: extremely high, high, medium, low and extremely low. The vulnerability of the towers at 15 transmission towers within the surrounding area of the Hongxing Coal Mine was finally evaluated, and the evaluation results were consistent with the on-site investigation. This research results can provide a scientific basis for the construction of the power grid disaster prevention system and risk control in coal mine goaf area.
