【摘要】：基于礦區(qū)開采沉陷具有沉降速度快、量值大的特點(diǎn),針對(duì)使用合成孔徑雷達(dá)干涉測(cè)量(InSAR)技術(shù)難以正確獲取煤炭開采引起的地表下沉的全盆地信息的問題,提出了基于小基線集(SBAS)技術(shù)的概率積分法(PIM)獲取礦區(qū)沉降量的方法。試驗(yàn)以陜西某礦52304工作面為例,首先采用SBAS技術(shù)得到下沉盆地邊界,然后結(jié)合少量SBAS獲取的邊界點(diǎn)和RTK監(jiān)測(cè)點(diǎn)(沉降量≥300mm)反演概率積分法參數(shù)及下沉盆地,最后將反演的盆地中心與SBAS獲取的邊界融合,完成了地表沉降的全盆地信息的提取。結(jié)果表明:52304工作面走向、傾向最大沉降量相對(duì)誤差分別為0.2%、6.0%,該方法可以有效地解決In SAR技術(shù)無法監(jiān)測(cè)礦區(qū)大梯度沉降問題,為In SAR技術(shù)在礦區(qū)開采沉陷監(jiān)測(cè)提供了新的用途。
[Abstract]:Based on the characteristics of high subsidence speed and large value of mining subsidence in mining area, it is difficult to obtain the whole basin information of surface subsidence caused by coal mining by using synthetic Aperture Radar Interferometry (InSAR) technology. This paper puts forward a method of obtaining the settlement of mining area by probability integration method based on small base-line collection (SBASS) technique. Taking 52304 face of a mine in Shaanxi province as an example, the boundary of subsidence basin is obtained by using SBAS technique. Then the parameters of probabilistic integration method and subsidence basin are inversed by a few SBAS boundary points and RTK monitoring points (subsidence 鈮，
