摘要

晋西黄土丘陵地区地形复杂,冲沟发育,黄土层地表受煤炭开采影响后地表移动变形剧烈,地表移动变形十分复杂,容易引发地裂缝、崩塌、滑坡等地质灾害。为确保地面高压输电线塔安全使用,通过对黄土丘陵区地表采动变形及损坏特征及地表高压输电线塔抗采动变形能力分析,文中提出了高压输电线塔保护性开采方案,并对高压线塔采取安全保护措施,实践表明采后未影响高压线塔的安全使用。
Abstract

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.
