| 摘 要： | 根据反井钻井在坚硬岩石钻进中出现的滚刀破岩效率低、使用寿命短等问题,研制了新型镐形刀齿。通过破岩试验,镐形镶齿滚刀有较好的破岩效果,适合于在硬岩及中硬岩层中推广应用。

| Abstract: | According to the low rock breaking efficiency,short service time and other disadvantages of the rolling cuter in the hard rock drilling of the mine shaft rising boring,a new pick shape tooth rolling cuter was developed.With the rock breaking test,the pick shape inserted tooth rolling cuter has obtained a rock breaking result and is suitable to be applied to the drilling in the hard rock and medium hard rock. |
