Abstract: Based on two scenes ALOS PALSAR data,the surface subsidence field of mining area during the period from 2007-12-10 to 2008-01-25 is obtained by using D-InSAR technology.Then,the D-InSAR monitoring value is used to extract the advance influence angle of the mining working face in the mining period and compare with the measured data.The experimental result shows that it is feasible to obtain the advance influence angle of the mining working face by using D-InSAR technology.The probability integral parameter inversion method which is based on simulated annealing algorithm (SA) is adopted to obtain the probability integral parameters of the mining working face under the incomplete mining.The result shows that it is feasible to calculate the probability integral parameters of mining working face by using parameter extraction method of probability integral parameter based on SA.The research results play an important rule in movement and deformation monitoring in mine areas by D-InSAR technology.
