摘要
依据典型浅埋煤层工作面的实测和模拟，发现了采场老顶初次破断的非对称现象。运用相似模拟和理论分析相结合的方法，揭示了采场顶板初次破断机理，确定了有关参数。
By field observation and simulating test of shallow seam longwall mining,the phenomenon of main roof asymmetry breaking is discovered during the first weighting.Based on simulating model test and theoretical analysis,the mechanism of main roof first breaking is revealed,and the asymmetry breaking parameter is determined.
