Understanding the coupled interaction of rock and water under stress is often a key factor in assessing slope stability in open pit mining. In this paper, a numerical modeling research project is presented which demonstrates the concept of hydromechanical coupling (HMC) and assesses the sensitivity of contributing parameters to pressure responses observed in a piezometer sensor due to excavation of a mine slope. Site monitoring data showing HMC effects within a mine in Nevada are analyzed and reproduced using FLAC. This research aims to promote the understanding of HMC in pit slopes and provide improved guidance on how to plan mining activity, monitoring and slope design to incorporate the benefit of HMC effects.
