摘　　要：以甘肃华亭某矿特厚急倾斜煤层开采为研究对象,采用开采沉陷预计和开采实践,针对采动影响区多基高压线塔进行了首采面开切眼优化设计。揭示了不同开切眼位置对各基高压线塔的采动影响情况,得出了各塔塔顶偏移量与开切眼位置的关系曲线,分析了高压线塔与工作面的相对位置和塔顶偏移量的关系,确定了首采面开切眼优化位置,进行了开采实践和地面监测。在未采取任何纠偏维护措施的情况下,地面10基高压线塔均安全运行,说明首采面开切眼优化位置基本合理,可为类似的多基高压线塔下采煤提供依据。In order to optimizing open-off cut location of first mining face in extremely-thick and steeply-inclined coal-seam in a mine of Huating Coal, mining influence of different open-off cut location on every high-voltage line tower was revealed. The relationship curve of offset of tower top and open-off cut location was obtained and national open-off cut location was decided. By mining practice and surface monitoring, it was found that all high-voltage line towers were in safe operation without applying any protection measures, which showed that the open-off cut location was rational and could provide reference for similar condition.
