本文根据使用新技术──双回路注（放）水系统在６３上１０工作面综采放顶煤开采覆岩破坏的探测结果，结合其它采矿方法的实测结果，应用断裂力学理论，研究了放顶煤开采覆岩移动变形破坏特征，为矿井安全生产提供了依据。
Based on the detection results of overburden destruction in fully mechanized top coal caving mining on 63 to 10 working face with new technology ─ ─ double loop injection system, combined with the measured results of other mining methods, the theory of fracture mechanics The characteristics of moving deformation and failure of overlying strata in top coal mining provide basis for mine safety production.
