Advanced GNSS technology of mining deformation monitoring

Innovation of the mining deformation monitoring technology has been aroused with the development of GNSS technology. This paper probe into the feature of mine Continuously Operating Reference Station (CORS) and precise height difference model was constructed in Yanzhou and inner Mongolia to practise the technology. Based on the technology of mining CORS, we proposed the mining 3D deformation monitoring technology of large area. Based on the technology of RTK, we proposed the mining subsidence monitoring technology of small area. Based on the construction of the model of height difference, GNSS-RTK technology was proposed to be used in subsidence monitoring. This paper provides specific ways to the modernization GNSS monitoring technology in mining deformation.
