摘要
本文结合刘庄矿业有限公司首采面地表移动观测站的高程连接测量和第一次全面观测,设计了首采面地表移动站的三等水准控制网,利用抗差估计模型剔除粗差,结合最小二乘估计模型对观测结果进行了处理,并从精度、可靠性和置信度等三个方面进行分析并得出结论。为以后采集各个阶段的地表移动数据,求出参数并且得出结论提供有效的基础数据,从而为刘庄矿的后期采煤提供有效的技术保证。
Combining the height connecting measurement and the first comprehensive observation in Liuzhuang Mining Corporation first work face ground surface movement observation, a third leveling control networks was designed. The gross errors were eliminated using the robust estimation model. The observed result was processed using least square estimation model. Conclusions were obtained by analyzing the accuracy, reliability and confidence, which provides basic data for various stages of ground movement data acquisition and parameters deriving and conclusion obtaining, so as to provide effective technology guarantee for LiuZhuang post -mining.
