Abstract: In order to obtain real-time dynamic deformation and deformation trend of railway above goaf,a method based on the combination of the Differential SAR Interferometry (DInSAR) technique and probability integral method was presented in this paper. Firstly,the DInSAR technology was used to monitor the goaf,and the monitor results were compared with leveling data.Then,the probability integral method parameters were calculated using DInSAR monitoring results, and modified the prediction parameters into sufficiency mining condition.Finally, the deformation of the railway was predicted using the modified parameters. The results verified the combination of both can effectively monitor and predict railways and other linear structures.

Key words: DInSAR, deformation monitor, probability integral method, goaf
