摘　　要：我国牙轮钻机的发展经历了一段艰苦创业的过程。本文论述了科技工作者从解决钻孔偏斜问题出发，进行了广泛而深入的调研、论证，进而研制出ＫＹ—１２０型、ＫＹ—１７０型牙轮钻头和相应的钻具，既满足了新兴的大直径深孔采矿法凿岩的需要。The development of rotary drill has experienced a course of hardly pioneering work. Proceeding from solving the problem of hole deviation, the science and technical workers has made wide and deep investigations and demonstrations, and then developed model KY120 and KY170 rotary bits and their drilling strings. These drills not only meet the requirements of drilling in new largediameter longhole stoping, but also open up a new way to expanding hole from top to bottom.
