Abstract
The majority of coal mines in India use open-cast mining method to extract coal. The amount of overburden produced by the mine is increased as a result of the increased working depth and higher stripping ratio. Land scarcity is the major problem of the overburden management with stability in the mine area. Optimizing the dump geometry is an alternative way of overburden management in the mine area with stability. This investigation addresses the effect of seismic loading on the dump with the different geometric configurations. This study used the finite difference method-based numerical solver (FLAC2D software). The numerical model results show that the dump is stable under static conditions. The investigation results show that the dump slope toe is sensitive to dynamic conditions. This investigation results will be helpful for the identification of susceptible zone in the dump slope. And based on this investigation results can make decisions for real-time slope monitoring sensor installation in the critical zone.
