地质系统近几年发生的塔架碰高压线触电事故就有近十起之多。这些事故大体可分为三种类型。第一类是因为地质部门把钻孔孔位设计在高压线下或高压线附近、在安装和竖起塔架时、塔架碰高压线引起触电事故如广东某队由于将孔位设计在高压线下，钻工把100型钻机的钻架抬放在距1万伏高压线不足1m处停放，待又继续向高压线靠近时，高压线与钻架间引起猛烈的电火花放电，使6名抬钻架的钻工同时触电
In recent years, geological systems have hit nearly ten electric shock accidents on towers and high voltage lines. These accidents can be roughly divided into three types. The first type is because the geological department designed the hole hole position near the high voltage line or near the high voltage line. When installing and erecting the tower, the tower hit the high voltage line and caused electric shock. For example, a team in Guangdong drilled the hole position under the high voltage line. The worker raised the drill frame of the 100 drill rig to a distance of less than 1m from the 10,000-volt high-voltage line, and when it continued to approach the high-voltage line, a violent spark discharge was caused between the high-voltage line and the drill frame, so that six drilling rig drillers At the same time
