Analysis of Surface Subsidence in Coal Mining Based on Surfer
With the mining of underground coal,the farmland and buildings are damaged due to surface subsid-ence.The surface movement observation station is set for the working face in Huainan mining area,and the Sufer8.0 is used to process the ground surveying data,and the 3D visualization map of subsidence basin of each phase is generated.The subsidence influence distance of the main section of the strike and dip in each phase is ob-tained,and the surface subsidence influence area is calculated.The subsidence basin and the dynamic evolution law of subsidence area is analyzed.The study can provide some technical support for scientific mining and com-prehensive environmental treatment.
