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。 In the process of mine rescue and rescue, rescue workers or some rescue items are needed. The life-saving system goes down as soon as possible and reaches the affected area quickly. It is a commonly used and effective method to deal with coal mine accidents by establishing a direct access to disaster areas through rescue drilling. The main research work is about the double-arm drill pipe used for ground drilling in the rescue system of coal mine, and the structure, mechanical performance, connection thread and torsional strength of the double-arm drill pipe are discussed.
