| 摘 要： | 为监测潘一东区1252（1）首采面开采引起的地表移动变形规律,布设了由1条全走向线和一条全倾向观测线、12个控制点和186个监测点构成的地表移动观测站.在采用GPS定位技术实施观测站平面连接测量过程中,为克服转换基准点中存在的位移对求解的转换参数的影响,采用了抗差估计理论,并建立转换后GPS网的质量评价模型.根据对GPS连接测量平面控制网的处理结果分析,采用抗差估计求参,有利于保留GPS技术高精度的特点.

| Abstract: | For monitoring the law of ground movement and deformation casued by Panyi east 1252 （1） first mining face, layouting the surface movement observation that consists of l entire trend line and 1 full orientation observation line, 12 control points and 186 monitoring point station. GPS positioning technique was used on measuring plane connected survey, in order to overcome the influence of existing converte datum transformation in solving conversion parameter, it adopted the robust estimation theory and established the quality evaluation model of the GPS network after convering. According to the outcome of analysis and processing on GPS plane control network, it adopted robust estimation to solve parameters and retained the characteristics of high precision GPS technology. |
