Application of Arranging Spot Freely in City Surveying and Mapping

摘要:

实际测量工作中，经常会碰到控制点丢失或不通视情况，本文介绍了自由设站法在城市中的应用。实践证明，该方法现场操作简单、精度可靠，有检核条件，完全能满足工程测量的精度要求。

Abstract:

Contact triangle measuring is the important method in introduing datas of ground controlling spot datas to well in order to guide underground mining. Contact triangle measuring was used in Xinhui and Jinxing gold mines when they were built 10 years ago. In May 2005, by using 54 coordinates and elevation 56 Yellow Sea Establishment of the ground control network, triangular shaft contact measurement and roadway traversing are carried out in two siloes seperately. It will help check breaks traverse points for two mines and provide a legal basis for dealing with cross-border underground mining.
