摘　　要：海域下厚煤层放顶煤的开采是中国的创举,以龙煤集团北皂煤矿的实际开采为例,详细阐述了海域下厚煤层开采“随动加载作用”对矿山压力显现的影响,只有充分了解和掌握矿山压力的运动规律,才能为安全高效开采提供可靠的保障。The mining of thick seams with sublevel caving method under sea area is the pioneering work of China. Taking the practical mining in Beizao Coalmine of Longkou Coal Mining Group Co. Ltd. as an ex-ample, this paper discusses the impact of ＂following loading effect＂ on rock behavior in detail. It concludesthat it is possible to provide the reliable guarantee for the safe and high effective mining of coal only withthe fully understanding and mastering the movement law of rock pressure.
