摘要
针对在矿山开釆过程中引起岩层和地表的沉陷,威胁矿区地表居民的人身和财产安全等问题。本文通过总结现有RTK-CORS技术的优劣,提出了一套改进的RTK-CORS测量系统,并对传统的Kalman(卡尔曼滤波)测算方法进行改进设计,经过改进后的整套系统应用于鄂尔多斯某煤矿的实地沉陷测算试验中,通过对测量数据的误差分析以及精度评估,验证了改进的RTK-CORS系统具有较高的精确度的同时也具有较高的可靠性与稳定性,为今后准确、高效测量煤矿开采区地表沉陷提供了研究参考依据。
For the mining process in the mining caused by rock and surface subsidence,threatening the surface of the mine residents and property safety issues.In this paper,an improved RTK-CORS measurement system is proposed by summarizing the advantages and disadvantages of the existing RTKCORS technology,and the traditional Kalman method is designed.The improved whole system is applied to the field subsidence of a coal mine in Ordos In the experiment,through the error analysis and accuracy evaluation of the measured data,it is verified that the improved RTK-CORS system has high accuracy and high reliability and stability,and it is accurate and efficient for the future.Regional surface subsidence provides a reference for research.
