Yun Jialing Coal Mining Subsidence Monitor Application Based On D-InSAR Techniques

This paper is intended by studying the D-InSAR technique applicability in mining areas, and thus the classic result of amendments to mining subsidence prediction model, to address the areas of coal mining subsidence prediction provide a new method. In this paper, the mine production data, the ground field observations, satellite remote sensing measurements and other means to collect the results of a comprehensive analysis of the static model of mining subsidence inversion experience in the parameters. For the study of mining subsidence bring new vitality; to expand the applications of new technologies; for the geological hazard warning to provide new ideas.A long history of coal mining, long-term underground mining activities resulted in large areas of mined areas, threatening the local ecological environment and people and property. Restricting local economic development has become a major factor and threatening the safety of future mine production. Therefore, the risk of mining subsidence carried out research work for the prediction of geological disaster prevention, safety green lead mine production, protection of national and people's lives and property between man and the coordinated development of the natural environment has important practical significance.Previous studies for mining subsidence often only focus on the analysis of rock mechanics factors. Simple physical model of the abstract, complex and difficult geological factors are widely used in mining production; Moreover, mining subsidence caused by many factors, the conditions of different mines and different.Although previous studies considerate as possible, but there are still more subjective factors, and forced the introduction of subjective parameters; even taking into account many factors can only build a static model, it is difficult for the early warning forecast.How to explore new theories, new methods to quantify these subjective parameters become the focus of future research. New remote sensing technology and computer technology for the exploitation of the quantitative study of subsidence provides a new way of thinking.Firstly, starting from the research situation, the essence of previous studies place; Secondly Differential SAR Interferometry (D-InSAR) technology in coal mining areas of the practical difficulties are analyzed and solved; and through the mine Kailuanlarge sample of D-InSAR subsidence monitoring technology in the mining results were evaluated; and based on the extraction of the mine subsidence area timing diagram of sample points, set up a "mining - mining subsidence" of the space-time relational model, introduced probabilistic model of integration, and use this model empirical parameters of mining subsidence inversion.
