Numerical Simulation and Evaluation of the Impact of Underground Mining on the Deformation of Surface Structures
To better reveal the impact of underground mining on surface structures,this paper focuses on the room and pillar mining meth-od of sulfur gold mine in Anhui.The FLAC3D was used to simulate and calculate the surface displacement after mining of ore bodies above+5 m.The deformation value calculation and analysis of the protected object area and the area with obvious displacement changes within the mining area movement zone were achieved.The simulation results show that the maximum surface deformation and curvature of work area occur within the range of cement silos,office buildings,and pump rooms.The overall surface displacement meets safety requirements,and relevant research methods pro-vide good reference for similar mines.
