Based on data information of Jiangsu Province continuously operating reference stations, the influence of the number and distribution of CORS reference stations to the solution accuracy of GPS network data were discussed combining with 6 stations solution of the GPS deformation monitoring network in a coal mine. The experimental results show that when processing regional GPS network, it's the best to select the CORS reference station as the reference frame, and the CORS reference station space distribution should be as uniform as possible, and the number reached 4, and there's no need to select the same side CORS reference station. The conclusion provides the basis to process GPS network data by selecting suitable CORS reference stations.
