Study on Mining Design and Stability of a Closing the Tailing Pond

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.
