Assessment of the Slope Stability Under Geological Conditions Using FDAHP-TOPSIS (A Case Study for Sungun Open Pit Mine)

Determining the degree of slope stability is one of the most important steps in the design of open pit mines that are affected by other mining activities. So that the collapse of a part of the wall will lead to irreparable human and compensatory damages. Slope stability is affected by natural factor...
