Abstract:

There are many factors to influence on the ground settlement in mined-out area. Based on the finite element software ANSYS, making use of the flexibility of numerical simulation method, the main factors are analyzed respectively. The Druker-Prager model is chosen, which is suitable to simulate the materials of rock and soil. ‘Kill Element’ command is used to simulate the situation of exploiting, and then the command of ‘Activate Element’ in ANSYS is used to simulate that the mined-out area is filled. The influence of each factor in the ground settlement over mined-out area is studied respectively such as depth, thickness of the mined-out area, the topographic condition and the filling of the mined-out area.The result shows that the ground settlement decreases with the increase of the mining depth, the ground settlement increases obviously with the increase of mining thickness, the basin movement will move to the lower direction with the change of topographty, and it will reduce the ground settlement evidently to fill the mined-out area in time after mining.

Key words: mined-out area, ground settlement, ANSYS, Drucker-Prager model
