中文摘要：

矿山变形监测是矿山安全开采与可持续发展的重要组成部分。基于GPS RTK技术，利用实地采集的观测数据，以静态相对定位结果作为参考，分析对中杆倾斜量对于RTK流动站水平和垂直点位精度的影响。研究结果表明，对中杆倾斜误差对RTK水平定位精度影响较大，但对垂直误差影响很小；采用三脚架模式，可获得毫米级的平面定位精度；而高程精度与点间高差相关性较大，只能达到厘米级的精度。

英文摘要：

Mining deformation monitoring is an important component to mining safety and sustainable development.Comparing with the static relative positioning results,the GNSS real time kinematic （RTK ） observation data collected in the field was used to analyze the effects of rover pole inclination angle on its horizontal and vertical positioning precision.The results show that the inclination of rover pole has greater impact on the horizontal positioning precision than the vertical positioning precision.The horizontal positioning precision of millimeter level can be obtained by using tripod mode.We obtain centimeter level vertical positioning precision due to its related to the height difference between points.
