基于CORS的网络RTK矿山开采沉陷监测方法研究

A Method of Mining Subsidence Monitoring Based on CORS Network RTK

首先提出基于CORS的网络RTK技术在矿山地表沉降监测中的应用,并对其在矿山沉陷监测中的应用方法及误差进行了分析,提出一种网络RTK与静态GPS观测相结合的空间修正模型用以提高网络RTK技术在矿山沉陷监测中的精度。应用此种方法对网络RTK的定位精度进行探讨分析,其结果表明:在技术措施制定合理和外业观测条件良好的情况下,基于CORS的网络RTK技术使用此种空间修正模型用于提高矿山沉陷监测的精度是可行的,能够极大地拓展工作范围,提高工作效率,具有广阔的应用前景。

This paper first proposed the technology of network RTK based on CORS has been widely used, an analysis for its application method and error of mine subsidence monitoring, a spatial correction model by the observations of network RTK combined with static GPS to improve the precision of network RTK Technology in Mine Subsidence Monitoring. Through case studies, the application of this method for network RTK positioning accuracy are discussed, and the results showed that ： develop a reasonable technical measures and good outside observing conditions in the ease, the network RTK technology based on CORS using this method for improving the mine subsidence monitoring precision is feasible, can greatly improve work efficiency and expand the working range, and it has broad application prospects.
