为掌握老采空区地表下沉规律,基于11景Radarsat-2影像数据,采用Sta MPS软件的PS方法对峰峰矿区某矿老采空区地表进行形变监测,获得了2015年5月~2016年3月该矿老采空区的地表沉降情况。分析结果表明:老采空区地表下沉速率呈周期性变化规律,总体呈下降趋势,靠近停采线附近下沉量较大,同时还建立了采空区工作面累积下沉与停采时间的关系式,为评价老采空区地表形变研究提供了基础。
To grasp the law of surface subsidence in old gob area, based on the Radarsat-2 image data of 11 scenes and the PS method of Sta MPS software, the surface deformation of the old goaf in Feng mine area was monitored. From May 2015 to 2016 In March of the mine old goaf surface subsidence. The results show that the surface subsidence rate of the mined-out mined-out area shows the regularity of cyclical variation, and the overall downward trend is that the subsidence near the cut-off line is large. Meanwhile, the cumulative sinking and stoppage of the working face of the mined-out area are also established , Which provides the basis for the study of the surface deformation in the old goaf.
