水准仪/全站仪测量、GPS、InSAR等矿区沉陷灾害监测方法存在劳动强度大、费用高、数据源受控、不能实时动态监测等缺陷.基于此,提出基于分布式CCD/GPS的矿区沉陷灾害动态监测方法,其实质是一种分布式伪SAR卫星的动态观测模式,在所选CCD元器件和GPS—OEM板符合精度指标要求的情况下,通过无线/有线传输设备实时地把观测数据传输到数据处理中心处理并进行相应分析,并对该方法的系统结构和数据处理流程作了详细阐述,该方法可对矿区或某重点区域进行连续动态的监测.
Leveling surveying, total station measurement, GPS (Global Position System) and InSAR( Interfer- ometric Synthetic Aperture Radar)technologies for mining subsidence disaster monitoring have some disadvan- tages, such as labor intensity, high cost, and their data source are controlled, moreover these methods cannot monitor mining subsidence disaster real-time dynamically. Therefore, a new dynamic monitoring method for mining subsidence disasters by using distributed CCD/GPS sensors is proposed. This method is a dynamical survey model, composed of distributed pseudo-SAR-satellites. Under the conditions of CCD and GPS-OEM sensors to content the precision requirement, the survey data is transferred to data processing center and pro- cessed real-time. At the same time the deformation result is analyzed. The systematic structure and data pro- cessing flow of this method are expatiated. And the method proposed can provide a novel technology to solve the continuous and dynamic monitoring problems of mining subsidence.
