Abstract
This paper attempts to evaluate the effectiveness of rock reinforcement on underground coal mine entries using analytical technique. A two dimensional finite element analysis has been carried out to see the difference in the 4-entry stability with and without rock reinforcement. A total of eight models with different thicknesses of the immediate roof layer, different material properties, and different anchorage horizons of the bolts were considered in the analysis to see how the safety factors of these entries can be improved.
