AMSS - Analysis of Multiple Seam Stability
Software by NIOSH
AMSS is a software program that helps to identify the location and likely severity of multiple seam interactions. Multiple seam interactions are a major ground control hazard in many US underground coal mines. The two most common types of interactions are:
- Undermining, where stress concentrations caused by previous full extraction in an overlying seam is the primary concern, and;
- Overmining, where previous full extraction in an underlying seam can result in stress concentrations and rock damage from subsidence.
