煤矿救生系统地面钻孔用双臂钻杆

Surface Drilling for Coal Mine Rescue System of Double Wall Drill Pipe

在进行矿井的抢险救援时,需要救援人员或一些救援物品、救生系统尽快下井,快速到达受灾区域,通过救援钻孔建立直达灾区的通道进行施救是处理煤矿事故的常用且有效的方法。主要就煤矿救生系统地面钻孔用双臂钻杆进行了研究,对双臂钻杆的结构,机械性能要求、联接螺纹和抗扭强度等进行了探讨。

During mine rescue, the rescue stuff and relief supplements ought to be in the mine as soon as possible, especially the disaster areas. A common and effective way to deal with coal mine accident is to establish a direct gallery to the disaster areas using rescue drilling. Mainly studies surface coal mine rescue system with double-wall drill, and discusses the structure of double-walled pipe, the requirement of its mechanical performance, the connection of thread as well as the strenghth of torsion.
