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

摘要:

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

Abstract:

In factual surveying and mapping, controlling spots and no sighting condition will always happen. The method of arranging spots freely in city surveying and mapping is introduced in this paper. It is proved that this method is very easy and has reliable precision which can meet the precision demand in engineering surveying.
