Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Parametric study of the micro-explosion occurrence of W/O emulsions

International Journal of Thermal Sciences, 2018
When a water-in-oil (W/O) emulsion droplet is heated, a phenomenon called micro-explosion (?-exp) may occur. Micro-explosion can be defined as the burst of the continuous phase (i.e. oil) by the energy of evaporation of dispersed droplets (i.e. water) and the volume expansion that goes with it.
