摘　　要：为了提高测量的效率和精度,矿山井下平面坐标测量通常采用三联架法,同样,高程测量时,可用三角高程测量代替水准测量。本文采用三联架法进行三角高程测量时,测量过程中只需记录棱镜和仪器到基座底部参数与首末站棱镜和仪器高差,便可推算起终点高差,提高了高程测量的速度和精度。In order to improve the efficiency and accuracy of the survey,the underground planimetric coordinate survey usually adopts the trigeminy tripod method.Similarly,the trigonometric leveling can be used instead of the leveling in the elevation survey.In this paper,when trigonometric leveling is carried out by the trigeminy tripod method,only the parameters from the prism and instrument of the original and terminal station to the base bottom and the height difference from the original and terminal station to the tripod head are recorded in the measurement process,then the height difference between the starting point and the terminal point can be calculated,and the speed and accuracy of elevation measurement can be improved.
