The paper analyzes the relationship between angle -measuring error and aligning error of underground control network and provides functional relation between angle -measuring error and the length of each traverse by the method of polynomial in order 2 with least-squares fitting based on statistical information of angle -measuring error.Therefore, adjustment mathematical model can be de-termined.Finally, an example further shows that the method above is able to improve the accuracy of adjustment .
