INFLUENCE OF WIDTH TO HEIGHT RATIO ON UNDERGROUND COAL PILLAR STRENGTH USING 2D NUMERICAL MODELLING ANALYSIS
The purpose of this study is to determine the influence of width to height ratio on coal pillar strength through a finite difference method numerical modelling. The coal pillar strength can be known from stress-strain curve. The pillars' widths range from 2.5 meters, 5 meters, 10 meters, and 15...
