The Information Acquisition System of Subsidence Mining-Induced Based on Mobile GIS

In order to solve the low efficiency, low inefficiency and low informationization problem of current mining subsidence acquisition technology backwardness, this paper provides a reliable and practical data acquisition terminal for mining subsidence monitoring and prediction work under CORS space information framework. This paper also adopts application of network RTK on the PDA communication between terminal and data center communication, Mobile GIS data organization, terminal and data center data fusion and other contents. The practice shows that this System greatly improves the speed and accuracy of the monitoring points’ information.
