利用二等水准测量对矿山沉降区监测中存在误差进行处理研究

The error in the monitoring of mine subsidence area is studied by using the second-class level measurement

社会经济与工业化的不断发展,推动了矿山行业的进步与发展,形成一、二、三、四个等级的水准测量。将二等水准测量作为精密水准测量中的重要组成部分,其在矿山沉降监测应用中范围日渐增大。但实践发现,在二等水准测量应用过程中仍存在诸多误差影响,影响测量工作质量。在工作经验总结上,就水准测量误差及其处理方法进行了分析,以供参考。

The continuous development of social economy and industrialization has promoted the progress and development of the mining industry,and has formed a level measurement of one,two,three and four levels.As an important part of precision levelling,the second-class level measurement is increasing in the application of mine settlement monitoring.However,it is found that there are still many errors in the application process of second-class level measurement,which affects the quality of measurement work.In the work experience summary,the level measurement error and its processing method are analyzed,for reference.
