Abstract:

The coal mine is an important one-time energy. It is significant for research destruction movement and deformation caused by the coal mining, classical probability integration method as commonly used in subsidence prediction has its own superiority, but it can’t show the movement and deformation within the strata, and the key parameters only be confirmed by actually measuring it, it caused some difficulty to the prediction of mining subsidence. The study shows that the numerical simulation of no need to determine the complex parameters not only can display the movement and deformation of the surface, but also can shows about the interior the rock stratum.

Key words: FLAC3D, ANSYS, Numerical Simulation, Probability integral, mining subsidence
