用虚拟平差法扩建矿区控制网的平差模型

Extension of Mining Area Network with Adjustment Function Model

本文通过对矿区控制网的恢复和扩建问题的研究,建立了它们的平差函数模型和随机模型,使在原有等级三角网基础上,以相同精度和相同技术规格由原网扩建或恢复同等级三角点,并保证原网点座标不改变,这一问题得以圆满解决。

This papar discusses the problem of renew and extension in mining area network. The adjustment function model and random medel of the new network are set up to make the network be extended on the same accuracy grade as the old one and the coordinates of the old network points keep unchanged.
