Research and application of RTK computer technology in mining area subsidence survey

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 RTK-CORS 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.
