潜孔钻机用稳杆器足VCR采矿法中防止炮孔偏斜的主要技术措施之一。采用合理结构、尺寸的稳杆器对保证炮孔设计要求极为关键。本文着重讨论三翼式刚性稳杆器的结构、尺寸与炮孔钻凿条件的匹配,以及有关稳杆器的使用问题。通过试验表明:这种稳杆器结构合理,尺寸随钻头特性而定。并且模索出一种解决稳杆器卡钻的有效改进方法。 Downhole drilling rig with a stable rod foot VCR mining method to prevent one of the main technical measures to defuse the hole. The use of a reasonable structure, the size of the stabilizer bar to ensure the design of the hole is critical. This article focuses on the three-wing rigid rod stabilizer structure, size and hole drilling conditions match, as well as the use of stable rod. The test shows that: This stable rod structure is reasonable, the size with the bit characteristics. And to find out a solution to the stick stabilizer stick effective method of improvement.
