Abstract: According to the many inner calculation procedures, complicated formula, cumbersome process, required data adjustment, long time consuming and pro ne 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 th e 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 ftted. The max coordinate difference after the adjustment was 1. 9 mm, 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 AutoCAD was proved. Meanwhile the diagram calculation intuition and the shortcut a dvantage 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 person nel.
