摘　　要：为了解某煤矿三矿区因长期开采所造成的地表沉陷情况,通过GPS技术对该区域的地下岩体移动状况实施监测,基于《测绘技术设计规定》等有关规范针对矿区建立监测网点,获取GPS位置数据,并通过Surfer软件对所获取的地理位置数据进行三维模拟,输出三维沉降模型,进而对该区域的沉陷情况进行判断。经三维模拟与数值分析发现,三矿区地表局部出现沉降小盆地,存在较为剧烈的地表塌陷,在加固处理之前不宜再实施煤炭开采作业。In order to understand the surface subsidence caused by long-term mining in the third mining area of a coal mine,GPS technology was used to monitor the movement of the underground rock mass in the area,and based on the"Regulations on Surveying and Mapping Technology Design"and other relevant specifications,a monitoring network was established for the mining area to obtain the GPS location data,and used Surfer software to perform a three-dimensional simulation of the acquired geographic location data,output a three-dimensional settlement model,and then judged the settlement of the area.After three-dimensional simulation and numerical analysis,it was found that there are small subsidence basins on the surface of the third mining area,and there were relatively severe surface subsidence.It was not suitable to carry out coal mining operations before strengthening treatment.
