摘要
以ZFYD2500型反井钻机为原型,针对该钻机在施工煤仓开始扩孔阶段出现的钻杆断裂事故,结合现场数据对钻杆进行力学分析和计算,总结出大直径反井钻机在扩孔施工中应如何避免钻杆断裂事故的发生。
In this paper,the ZFYD2500 type for the raise boring machine prototype, according to the rig in the construction of coal began to enlarge the hole of the stage is a broken accident of drill pipe,based on the date of drill pipe mechanics analysis ang calculation, summarizes the large diameter raise boring machine to enlarge the hole in the construction should be how to avoid drill fracture accident
