Abstract
The slope steadiness is influenced by slope configuration, material characteristics
and the applied forces interim both internally and externally. These forces encompass
the impact of water internally through pore water pressure, seepage forces and externally
through hydrostatic and hydrodynamic effects. Examining the slope under various
levels of submergence and drawdown illustrates the significant influence of water
on slope stability. The presence of water develops effective water pressure in open
pit slopes which is more concerned for slope pit designer and geotechnical engineers.
This study tried to discuss about the influence of drawdown and rapid drawdown conditions
for a mine slope stability in the light of slope stability studies under hydrogeological
characteristics. This study includes preliminary generalities considered for drawdown
conditions like soil properties, hydraulic properties and drawdown phenomenon.
