摘　　要：针对矿山两井定向内业计算步骤多、公式复杂、过程繁琐、需要进行数据平差、耗时长且易算错的情况,探讨了利用AutoCAD绘图软件的坐标展点、旋转、缩放、查询、距离和角度量测等功能进行两井定向的图解计算方法,并通过实例与传统计算结果进行比较。结果表明:测角闭合差、坐标闭合差和全长闭合差都是完全一致的,平差后的坐标差值最大为1.9 mm,最小为0.2 mm,符合《矿山测量规程》的要求。验证了AutoCAD图解计算精度的可靠性,同时显示了利用AutoCAD图解计算直观性和快捷的优点,为矿山测量人员解算两井定向提供了一种新的简便计算方法。According to the many inner calculation procedures, complicated formula, cumbersome process, required data adjustment, long time consuming and prone miscalculation of the two mine shafts orientation, the paper discussed that the diagram calculation method of the two mine shafts orientation was conducted with the coordinate points, rotation, scaling, enquiry, distance and angle measurement and other functions of the AutoCAD drawing software.A comparison was conducted on the cases and the traditional calculation results.The calculation results showed that the closure error of the measured angle, the closure error of the coordinates and the full length closure error were fully fitted.The max coordinate difference after the adjustment was 1.9 ram,the min was 0.2 mm and all were met with the requirements of the Mine Survey Regulations.The diagram calculation accuracy reliability of the AntoCAD was proved.Meanwhile the diagram calculation intui- tion and the shortcut advantage of the AutoCAD applied were showed and could provide a new easy calculation method to calculate the two mine shafts orientation for the mine survey personnel.
