| Abstract: | Borehole deviation is of importance for deep hole reconnaissance construction in the strong natural whipstocking stratum, it always affects the quality of the hole and the reconnaissance achievement seriously. Taking Hengshan＇ s mountain railway tunnel as an example, this article introduces the methods of bored deviation control and the correction with screw rod drilling tool in the gneiss layer of serious natural whipstocking stratum. |
