Analysis of Rock Movement and Surface Subsidence Prediction in Thin Coal Seam Mining
This paper expounds the construction of a coal mining model using a digital speckle system,and uses it to simulate the displacement of rock layers during coal mining.It applies the Beidou satellite navigation system to dynamically monitor the surface subsidence of the mining area,and finds that as the mining operation progresses,the surface subsidence of the main section gradually increases,with the maximum subsidence value approaching 1 600mm.
