Auto CAD在井下贯通测量中的应用

Application of Auto CAD in the underground through survey

在井下贯通测量中,交点坐标的计算及其重要,其准确性直接影响到贯通精度,传统的计算方法计算量大易出错,运用CAD软件直接提取交点坐标,更方便快捷不易出错,可大大提高工作效率。

In the underground through measurement, the calculation of intersection coordinates is important, its accuracy directly affects the holing through accuracy, the traditional calculation method is prone to error large amount of calculation, using the CAD software direct extracts the intersection coordinate, which is more convenient and less error prone, and can greatly improve the working efficiency.
