| 摘 要： | 矿区控制网的扩建是我国现阶段矿山测量上作的重点,对扩建了的控制网如何进行平差是近年来人们所关心的问题.本文提出了附限制条件的序贯平差法及其相应的Helmert型方差分量估计公式,并以一矿区控制网为实例,说明了该法的应用。文中提出的平差方法同样适合于其它上程控制网扩建时的平差。

| Abstract: | Expanding mining control network is now an important task of mining surveying in ourcountry's mine.How to adjust the expanded mining control network has aroused interest inrecent years.In this paper,the sequential adjustment with constraints and its estimative formulas of variance components of Helmert type are proposed.A practical example of expandedmining control net is given to illustrate its application.The adjustment method is simultane-ously suitable for adjustment of other engineering control net when expanded. |
