【 摘 要 】

The article presents the methodology of determining the impact of subsidence resulting from underground mining activity on the operation of overhead power lines. Exemplary results of calculations of stress in conductors has been presented. Also the method of defining the influence of factors that can mitigate the effects of land deformation, such as inclination of insulator chains and elastic deformation of overhead line towers and their crossarms, has been discussed.
