Application of GPS based on Beidou system in mine settlement deformation monitoring

将GPS技术与北斗定位系统有机的结合形成GPS实时动态监测系统,通过矿山地表沉降形变监测结果可知:该系统不仅具有较强的时效性,而且所获监测结果的精度更高;与传统的全站仪监测方法相比,者的误差值均小于1mm,说明基于北斗系统的GPS监测方法在矿山地表沉降形变监测中具有较高的精度和可靠的监测稳定性,所获数据的质量是可靠的,且监测精度能够满足矿山监测需求;通过监测实例分析可知,该方法能够精确的分析出形变方向、速率以及演化趋势等,为矿山安全生产提供了基础依据。

The GPS technology is organically combined with the Beidou positioning system to form a GPS real-time dynamic monitoring system,which can be seen through the monitoring results of mine surface settlement deformation:The system not only has strong timeliness,but also has higher accuracy of the monitoring results obtained;Compared with the traditional total station monitoring method,the error value of the person is less than 1mm,indicating that the GPS monitoring method based on the Beidou system has high accuracy and reliable monitoring stability in the mine surface settlement deformation monitoring,the quality of the obtained data is reliable,and the monitoring accuracy can meet the needs of mine monitoring;Through monitoring case analysis,it can be seen that the method can accurately analyze the deformation direction,rate and evolution trend,etc.,which provides a basic basis for mine safety production.
