| 摘 要： | 由于哈尔乌素露天矿排土场特殊的黄土地质条件以及主坝与排土场之间大量积水的存在,对排土场边坡稳定产生极为不利的影响。采用FEPG软件,探讨了积水入渗、毛细水作用对排土场边坡变形破坏产生的影响,揭示了弱层演化成含水层的全过程,得出在水的长期浸润下,边坡稳定系数逐渐减小的结论,并提出相应的解决措施以满足煤矿生产与安全要求。

| Abstract: | Because of the special loess geological condition of the dump in Haerwusu open-pit mine and the plenty ponding water between the main dam and dump,it brings bad influence to the slope stability of the dump.We used FEPG software to discuss degeneration damage caused by ponding infiltration、capillary water,it revealed the overall process which weak layer turned into aquifer,we came up with a conclusion that coefficient stability would decrease under the circumstance of being infiltrated and the solution came out as to satisfy the production and safety requirement for the coal mine. |
