摘　　要：兴隆庄煤矿三采区下部上方存在兴庄II线110kV、马青-曲阜220kV高压输电线各一路,由于采取了精准变形预计和分析,在高压线未搬迁情况下,顺利采出了高压线下压覆的煤炭资源,提高了资源的回收利用率。本文针对兴隆庄煤矿高压线下压煤开采实践进行了分析总结。进行精准预测表明,开采与治理技术在有效掌控地表变形和高压线塔及时维护的前提下,可实现煤炭资源的安全合理回收,高压线下压煤开采具有重要的指导意义。There is a 110kV Xingzhuang II line and a 220kV Maqing-Qufu high voltage transmission line above the lower part of the third mining area of Xinglongzhuang Coal Mine.Due to accurate deformation prediction and analysis,the high-voltage line was successfully mined without the high-voltage line being relocated The overwhelmed coal resources have improved the recycling rate of resources.This article analyzes and summarizes the coal mining practice under the high-pressure line in Xinglongzhuang Coal Mine.Accurate prediction shows that the mining and treatment technology can effectively control the safety of the coal resources under the premise of effective control of ground deformation and timely maintenance of high-voltage line towers.Coal mining under high-pressure lines has important guiding significance.
