Pit Wall Depressurization Using Horizontal Drains: …

Horizontal drains (HDs) are commonly deployed at open pit mines to depressurize the pit walls and thereby improve pit wall stability. If successful, depressurization maintains current pit wall angles and improves stripping ratios, which directly influences mine economics. HDs are commonly designed using empirical approaches that have been developed based on …
