Simulation of narrow coal pillar width in gob-side entry driving
Numerical simulation of coal pillars with different widths in goaf excavation at 1102 working face of Huacaoan Coal Mine is carried out to study the influence of different widths of coal pillars on the stability of surrounding rock in goaf excavation. Finally, the width of coal pillars is determined to be 5m, which ensures the safety of roadway excavation, improves the utilization rate of coal extraction and responds to the call of green mining.
