| 中文摘要: |
| 湖南省隆回县金山矿区地层板理发育，造斜强度大，钻孔偏斜一直是制约该矿区钻探施工的瓶颈问题。通过采用钻孔初级定向与使用LZ型连续造斜器实施受控定向相结合的施工工艺，钻孔轨迹得到有效控制，成功解决了金山矿区钻孔偏斜问题，达到了地质预期目的。 |
| 英文摘要: |
| The Jinshan mining area, Longhui county, Hunan Province is characterized by well developed slate with numerous slaty cleavages, leading to borehole deviation that is the most serious problem in the drilling work. To overcome this difficulty, we adopt combination of primary borehole orientation and controlled borehole directional technologies using LZ-type continuous whipstock. It effectively controls the drilling trajectory, successfully resolves the borehole deviation problem, and achieves the expected geological purpose. |
