Safe mining of coal under high voltage transmission tower in loess hilly area

The loess hilly area in Western Shanxi was characterized by complex topography and gully development.The surface movement and deformation of the I oess stratum ground was intense after coal mining. The surface movement and deformation was very complex,which could easily lead to geological disasters such as gr ound fissures,ollapses and landslides. In order to ensure the safe use of ground high-voltage transmission towers,the protective mining scheme of high-voltage transm ission towers was put forward by analyzing the characteristics of surface mining deformation and damage and the anti-mining deformation ability of surface high-voltage transmission towers in Loess Hilly areas,and safety protection measures were taken for high-voltage transmission towers. Practice showed that the high-voltage transmi ssion towers safety use were not affected after mining by taking some protective measures.
