Abstract Due to the sensor limits and effect of noise and atmospheric delay, the maximum deformation gradient detected by InSAR technology has a limit. In order to accurately predict the detection ability of InSAR technology in deformation monitoring of mining area, this paper establishes the dynamic detection function model of maximum deformation gradient of InSAR based on the geological mining data of 65 mining areas, combined with Knothe time function and probability integral model, using TerraSAR data of different spatial resolutions. The model can use existing geological mining data to judge the detectable range of InSAR in different mining stages without SAR image in advance. In this paper, taking Daliuta mining area in Shanxi Province as an example, seven TerraSAR data from November 21, 2012 to January 26, 2013 are used for experimental verification. The results show that the model can accurately predict the detectable range and determine the detectable boundary of InSAR technology in different mining stages of mining area,which can provide important reference for the application of InSAR technology in mining area.
