平度市大庄子两竖井三角形联系测量精度分析

Precision Analysis of Contact Triangle to Two Siloes in Dazhuangzi of Pingdu City

三角形联系测量是地面控制点数据引入井下、指导井下开矿的重要手段。鑫汇金矿、金兴金矿已于建矿时进行联系测量,现已开矿10余年。2005年5月,利用54北京坐标系、56黄海高程系建立地面控制网,分别对两竖井进行三角形联系测量及巷道导线测量。对两矿巷道顶板导线点起到检核作用,为处理井下越界开采提供法律依据。

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.
