摘要:Numerical simulation analysis were done on breaking arch developing and evolving process of both single stope and coal seams mining field by FLAC3D. Results show that in single strope's advancing process, breaking arch's height would be different as strope's length changes, and breaking arch's height was decided by strope's length; in composite strope, as the coal pillar increasing, composite strope's breaking arch gradually develops from superposition state to independent state; as the strope's length changing composite strope's superposition state tend to balance
