摘　　要：在矿区初步勘查阶段,由于缺乏大比例尺地形图来设计勘探线时,会经常利用罗盘和GPS进行勘探线剖面实测,但这种测量往往造成与设计有所偏离,针对勘探线剖面测量数据偏离,拟建立一种平面几何方法进行校正。通过分段偏离角(α),利用三角正弦函数、余弦函数对矿区勘探线剖面简易测量数据进行校正,实践证明,该偏离校正是一种行之有效的方法。In the preliminary exploration, because of lack of large scale topographical map in exploration line design, people will carry out exploration line section survey with compass and GPS, which will cause the deviation from the design. We put forward a plane geometrical method to correct the deviation. According to the division of deviation angle （α）, the exploration line section simple survey data of orefield are corrected with the triangle function sin, cos. The practice shows it is an effective method
