穿孔爆破是露天矿生产中的首道工序。扎哈淖尔露天煤矿有6台燃油动力钻(下简称油钻),与电钻相比,油钻不受供电电缆的制约。钻机常频繁移动,在复杂环境中作业时,容易发生钻机侧滑、颠覆翻倒现象。钻机颠覆主要包括侧翻和正翻2种,常为侧翻,很少正翻。后来人们也将钻机从作业位置掉到工作面下方的情况称为严重颠覆。在不做特别说明的情况下,钻机颠覆即钻机的翻倒。1颠覆情况霍林河露天煤业从成立至今共使用过GD25C
Perforated blasting is the first process in the production of open pit mines. There are 6 sets of fuel power drill (hereinafter referred to as oil drill) in Zhahaer open-pit mine. Compared with electric drill, oil drill is not restricted by power supply cable. Rigs often move frequently, when working in complex environments, prone to slippery rig rig, subversion overturn phenomenon. Drill subversion mainly include rollover and are turning two kinds, often rollover, rarely turn. Later, people also called the rig a serious subversion when they fell from the work site to below the work surface. Drilling rig subversion is the tipping of rigs without special instructions. Subversion situation Huolinhe open-air coal has been used since its establishment GD25C
