高压输电线路杆塔采动变形规律研究

Study on Mining Deformation of Pole and Tower in High Voltage Transmission Iine

高压输电线路下压煤是许多矿区一种普遍存在的问题,研究高压输电线路杆塔采动变形规律具有重大的现实意义。文章对杆塔的采动变形规律进行了初步研究,根据杆塔所处位置不同,将工作面沿推进方向划分为五个区域,并分别阐述了杆塔处于每一区域的移动变形规律,总结了杆塔位于地表移动盆地不同位置移动变形规律的特点,并结合矿区实例进行了简要分析。

It is a common problem that high voltage transmission lines over mining area in coalfield. There is an important practical meaning to study the law of mining deformation of high voltage transmission pole and tower. This paper simply studied the law of mining deformation of tower. Based on different places of tower, divide a working face into five sections along mining direction and expound the law of tower movement and deformation in each area, also generalize characters of it.
