Overbreak prediction in underground excavations using hybrid ANFIS-PSO model

In underground excavations and tunneling, several methods used for excavating process. Drilling and blasting is one of these methods, which are globally used for rock excavation due to low investment and high flexibility against ground condition variations. However, negative effects of blasting to the peripheral rock mass around the excavation are inevitable. One of these blasting damages known as overbreak phenomenon and must be predicted and...
