爆破孔牙轮钻进的特点是钻进过程中通常伴随有极强烈的振动,因而,钻机的工作机构承受巨大的静载荷和动载荷。在牙轮钻头上端或钻杆之间加稳杆器稳定钻杆是降低这种载荷的方法之一。很久以来,在深孔钻进中就已采用稳杆措施防止孔斜。也应指出,采用稳杆器降低穿孔成本外,也能使穿孔速度平均提高 Blast hole drilling is characterized by diamond drilling is usually accompanied by a very strong vibration, therefore, the drilling rig’s work mechanism to withstand the huge static load and dynamic load. One of the ways to reduce this load is to stabilize the rod at the top of the cone bit or between the drill rods. For a long time, steady rod measures have been adopted to prevent hole slash during deep hole drilling. It should also be pointed out that the use of stable rod to reduce perforation costs, but also make the average perforation speed
