500 kV集庆线压覆矿产及采空区分析与评价

摘要

Transmission line often goes through goaf area in the power grid construction,especially goes through coal mine goaf area.It has practical significance and guarantees the safety of power grid to evaluate the impact of goaf sink on the transmission line and take the correspondent measures.Through the on-site investigation,analysis and evaluation for the mineral resources below the transmission line, the design basis of the plan path and scheme of tower foundation are provide.%电网建设中输电线路经过采空区尤其是煤矿采空区的现象已属常见，评价采空沉陷对输电线路的影响规律以及采取相应的应对措施，对保障电网的安全稳定运行，具有实践意义。文章通过对线路路径所经煤田地段的压覆矿产情况进行了实地的调查、分析，并对采空区进行了评价，为线路路径方案及铁塔基础方案提供了依据。
