【摘要】：礦區(qū)開采沉陷具有沉降速度快、量值大的特點,針對使用合成孔徑雷達干涉測量(InSAR)技術(shù)很難正確獲取煤炭開采引起的地表下沉全盆地信息的問題,提出融合D-InSAR和Offset-tracking技術(shù)提取礦區(qū)沉降信息的方法。試驗以陜西某礦52304工作面為例,分別采用D-InSAR和Offset_tracking技術(shù)提取了下沉盆地微小及大梯度形變信息,分析了D-InSAR中失相干問題和Offset_tracking的監(jiān)測優(yōu)勢,最后將兩者得到的結(jié)果進行融合,獲取了工作面上方的時序形變圖,實例中最大下沉處的相對誤差為0.5%~7.3%。結(jié)果表明,Offset-tracking可以有效解決D-InSAR無法監(jiān)測礦區(qū)大梯度沉降的問題,該方法可為礦區(qū)開采沉陷監(jiān)測提供新的技術(shù)手段。
[Abstract]:Mining subsidence in mining area has the characteristics of high subsidence speed and large value. In view of the problem that it is very difficult to obtain the information of the whole basin of surface subsidence caused by coal mining by using synthetic aperture radar interferometry (InSAR) technology.A method of extracting settlement information of mining area by combining D-InSAR and Offset-tracking technology is presented.Taking 52304 face of a certain mine in Shaanxi province as an example, the information of small and large gradient deformation in subsidence basin is extracted by D-InSAR and Offset_tracking techniques, and the problem of D-InSAR incoherence and the advantages of Offset_tracking monitoring are analyzed. Finally, the results obtained from the two methods are fused.The time series deformation diagram above the working face is obtained. The relative error of the maximum subsidence in the example is 0.5 and 7.3.The results show that Offset-tracking can effectively solve the problem that D-InSAR can not monitor the settlement of large gradient in mining area, and this method can provide a new technical means for mining subsidence monitoring in mining area.
