摘　　要：为避免煤矿生产中利用区域公共点联测和利用转换参数计算等方法获取CGCS2000坐标所付出的巨大人力和经济成本,本文通过IGS站点数据,利用速度场格网模型,求解工程控制点坐标,并与利用传统CGCS2000坐标获取方法获取对比,结果表明:基于IGS站点的煤矿CGCS2000坐标获取方法精度能够满足工程需要,GPS观测网具有较高内符合精度。In order to avoid the huge labor and economic cost of using regional common point joint measurement and conversion parameter calculation to obtain CGCS2000 coordinates in coal mine production, this paper uses IGS site data and velocity field grid model to solve engineering control point coordinates, and compared with the traditional CGCS2000 coordinate acquisition method. The results show that the accuracy of coal mine CGCS2000 coordinate acquisition method based on IGS site can meet the needs of engineering. The GPS observation network has high internal coincidence accuracy.
