Roadway side of coal pillar for the isolation and maintenance of gob roadway, the pillar is the main supporting role, the pillar on the roof rock deformation and failure of the control law has a great influence. The comprehensive analysis of gob-side small pillar of the mechanical condition and failure mechanism, we reached the edge of coal to balance the stress limit at any point of stress and yield zone width calculation. This is the follow-up study, by strengthening the support to improve the extent of the damage of coal pillar, pillar to maintain the stability of small coal pillar width rationally determine the methods, and provide a theoretical basis.
