Research and development of Field Data Collecting Synchronously System of Mining area

In order to grasp the changing situation of ground subsidence and surface collapse caused by underground mining in mining area, and improve the efficiency of field data collecting, this paper presented the architecture and functions of a Field Data Collecting Synchronously System (FDCSS). According to the FDCSS schema, mobile devices used Web Services to synchronous data with the server computer. It got cache map from server by Map Services, corrected the spatial data by using GPS differential information, and updated the subsidence attribute data to server databases by Web Services. Based on the introduction of the related technologies, the paper also gave the implementing result at Yanzhou Coal Mining Company Limited mining area. The FDCSS will provide high precision and lasted data for monitoring the deformation of the subsidence or collapse dynamically, and simplify the field deformation data collection procedure.
