摘要：
Flow-deformation coupled unsaturated soil model is built based on rainfall infiltration condition and modified Mohr-Coulomb failure criterion according to modeling a tailing dam with ABAQUS software. A few conclusions are obtained by adopting proper hydraulic curve soil water characteristic curve and compared with actually measures data. Studies yields provide foundations for simulation analysis on tailing dam on the condition of rainfall infiltration.

摘要：
Longtime existence of the mined-out region brings enormous security potential risk to the residents living in ore area. The model of the mined-out region underground has been established and calculated, and the effect of mined-out region on ground subsidence has been analyzed. The analysis result shows that the deformation of the roof of the mined-out region has significant influence on the ground surface and measures must be carried out immediately. Finally, the rational measures for treating the mined-out region are given to ensure the smooth and safe operation of the follow-up mining.

摘要：
There are many parameters influencing mining induced surface subsidence. These parameters usually interact with one another and some of them have the characteristic of fuzziness. Current approaches to predicting the subsidence cannot take into account of such interactions and fuzziness. In order to overcome this disadvantage, many mining induced surface subsidence cases were accumulated, and an artificial neuro fuzzy inference system(ANFIS) was used to set up 4 ANFIS models to predict the rise angle, dip angle, center angle and the maximum subsidence, respectively. The fitting and generalization prediction capabilities of the models were tested. The test results show that the models have very good fitting and generalization prediction capabilities and the approach can be applied to predict the mining induced surface subsidence.
