| 中文摘要:简要介绍了几种主要钻孔轨迹数学模型。将4个钻孔的测斜数据代入不同的钻孔轨迹数学模型中，并将运算结果与这4个钻孔深部被揭露点的坑内实测坐标进行对比，结论是不同钻孔轨迹数学模型对钻孔的定位差异给地质作图不构成重大影响。 |

| Abstract:Several mathematical models for borehole courses are introduced. The inclination measurement data of four boreholes are substituted in different mathematical models with the calculation results compared with the in site measured co ordinates of the deep pit exposed points of these boreholes. It is concluded that the orientation differences between different mathematical models for borehole courses don't affect the geological mapping significantly. |
