Coal mining area occurred in the settlement, may occur slowly, may also develop rapidly, in order to ensure safe production, you have to through certain technical means to monitor the settlement. Synthetic Aperture Radar Differential Interferometry D-InSAR has been developed rapidly in recent years and has been proved to be a very efficient for monitoring ground deation. It is possible to obtain continuous ground deation related ination within the short time interval of the test area, measurement accuracy can reach the millimeter level . Researchers at home and abroad have conducted a number of studies on the use of D-InSAR technology to monitor surface subsidence in the mining area. In 2009, Hanssen R et al. Used D-InSAR techniques to study the subsidence of the Wieliczka salt mining area in Poland Area of the surface deation data; In 2012, James Donovan et al. Conducted a study using the D-InSAR in the Book Cliffs coal mine area of Utah in the western United States, and obtained the three-dimensional surface deation map of t Based on the acquired PALSAR radar image data, the data processing flow and related commands of the “two-track“ difference are introduced in detail based on the D-InSAR technology processing software GAMMA developed by GAMMA Company in Switzerland, and the two-track differential is used to remove the ground The effects of different algorithms on the error are discussed.he test area; The domestic researcher Ren Xiaocheng and other use of PALSAR satellite L-band radar data, the Qinghai-Tibet Plateau area for differential treatment, access to the region of permafrost deation map, and demonstrated the D-InSAR in the Qinghai-Tibet Plateau permafrost area to carry out the possibility of deation monitoring. Because the space- time incoherence and atmospheric effects and other factors will affect the D-InSAR monitoring results ,In order to be able to effectively solve these effects, in recent years, the development of permanent scatterers PS, small baseline set SBAS, least squares LS, and so on other time-based deation analysis s, for monitoring a long time on a 万方数据 东华理工大学硕士学位论文 IV wide range of surface rough deation of these s is very effective, can quickly analyze the evolution of the experimental area and settlement development. Compared with the previous studies, the experimental area is located in the western part of Jiangxi Province, which belongs to hilly terrain, mountain dense forest, rich vegetation and seasonal effect. It has certain characteristics for D-InSAR research. Of the geographical relevance, can achi Based on the acquired PALSAR radar image data, the data processing flow and related commands of the “two-track“ difference are introduced in detail based on the D- InSAR technology processing software GAMMA developed by GAMMA Company in Switzerland, and the two-track differential is used to remove the ground The effects of different algorithms on the error are discussed.eve a certain value of research. In this paper, a coal mine in Fengping of Jiangxi Province, for example, the theory and of surface subsidence monitoring are discussed by using D-InSAR technology and Small Baseline Subset; Based on the semi - parametric gray model, the GM 1,1 model under the compensation least squares criterion is used to simulate the ground subsidence mechanism of coal mining area by D - InSAR technology. The main research contents include 1 The basic theory and implementation of D-InSAR technology are briefly described, and the error source of D-InSAR technology is briefly discussed. 2 Based on the acquired PALSAR radar image data, the data processing flow and related commands of the “two-track“ difference are introduced in detail based on the D-InSAR technology processing software GAMMA developed by GAMMA Company in Switzerland, and the two-track differential is used to remove the ground The effects of different algorithms on the error are discussed.The PALSAR radar image data of long band is combined with the “two-track“ differential to obtain the surface deation field of the mining area, and the level data are used to verify D -InSAR technology to monitor the accuracy of the results. 3 In order to solve the problem of error in time difference and elevation DEM in conventional D-InSAR technology, the time series subsidence map of experimental surface is obtained by using advanced D-InSAR technique - small baseline set SBAS As well as cumulative deation. 4 Based on the semi-parametric gray model, GM 1,1 and semi-parametric GM 1,1 model were used to fit the D-InSAR technique to fit the data. Then analyzed the fitting precision of the two models. Semi-parameter GM 1,1 model for prediction. On the one hand, it can break the limitation of the traditional adjustment model, on the other hand, make the mathematical model and the objective reality closer together, and calculate the error of the mathematical model nonparametric component and the accidental error , The mechanism of ground subsidence in coal mining area can be calculated and calculated by using the ination obtained in the observation value more fully.
