摘要：

The line structures situated in the undermined area are impacted and endangered by the underground mining. The present article focuses on impacts of mining on the high voltage transmission lines. Theoretical calculations are illustrated by a practical example for specific conditions including the evaluation of the behaviour of this line structure within the subsidence basin. We discuss the behaviour of the transmission towers, their movements, i.e. not only subsidence but also inclination, which result in stress or, on the contrary, in bending of the conductors and if the allowable stress of the conductors is surpassed, it could damage the conductors.
