Abstract Some displacements and deformations for the mine shaft working over past many years’ may occur.Curtain grouting is one of efficient methods for protecting the shaft and the surface around the shaft from the harm. The deformation caused by grouting around mine shaft is monitored with a reasonable scheme and the measured data are processed with the timeseries theory to analyze and forecast the dangerous deformation. Through analyzing different time series at different monitoring points, it is found out that the degree of forecasting precision and the accuracy ratio of forecasting model established with meaninterval timeseries are best.
