Time Series Forecasting Model of Ground Surface Deformation for Coal Mine Shaft

Abstract:

Some displacement and deformation for the mine shaft over past many years’ working may occur, which will cause heavy harm to both shaft itself and workers in well. Curtain grouting is one of efficient methods to protect the shaft and the earth’s surface around the shaft from the harm. The deformation caused by grouting around mine shaft is monitored with a reasonable scheme and the monitoring data are processed with the time-series theory to analyze and forecast the dangerous deformation. The paper analysis different time series of different monitoring points, finds the degree of forecast precision and the nicety ratio of forecast model are best.
