【 摘 要 】

The limitations of the traditional methods of assessing the surface subsidence and the state of structures and natural objects in mining operations are shown. An innovative approach to predicting the surface subsidence during tunneling is proposed. A model has been developed to forecast and estimate the land surface subsidence and deformation at any point of the displacement trough in an arbitrary direction at various stages of the tunneling. The model can be used not only at the design stage of tunnels, but also in the process of their construction.
