摘要
后方交会是煤田地质勘探工程测量常用的测量方法之一。本文根据煤田地质勘探的特点，推导出一种采用逐次迭代法解算后方交会角δ、γ，进而求得未知点（钻孔）坐标的计算公式。
The resection method is one of conventional geologic survey in coalfield.According to properties of coalfield geologic survey,the calculation of resection angular δ,γ is derived using successive iteration method,resulting in calculation formula for coordinate of unknown borehole.
