对销库尾矿库进行尾矿回采，是提高矿产资源利用率的有效途径，而滑坡、溃坝等灾害
事故在销库工程中频发。为探究出高效经济的回采方式，以多雨潮湿地区某尾矿库销库工程为例，
通过分析技术条件进行方案设计，并基于数值模拟手段进行稳定性分析。结果表明：该尾矿库宜采
用坝前干式+库内湿式的联合回采工艺，按由内到外、先库后坝、从上至下、单层开采的顺序进行回
采，在回采过程中坝体稳定性均符合安全要求。
Tailings mining is an effective way to improve the utilization rate of mineral resources，and
disasters such as landslides and dam breaks occur frequently in the project of closing the tailing pond. In or⁃
der to explore the efficient and economical mining method and safety，taking the closing the tailing pond
project in a rainy and humid area as an example，the scheme design is carried out through analyzing the
technical conditions，and the stability analysis is carried out based on numerical simulation. The results
show that the combined stoping process of dry stoping in front of the dam and wet stoping in the reservoir
should be adopted. The stoping sequence is carried out according to the principles of from inside to outside，
from reservoir to dam，from top to bottom and single-layer mining. The stability of the dam body meets the
safety requirements during the stoping process.
