摘　　要：综采放顶煤开采一次采出厚度与覆岩运动范围成倍增加，采动应力大．以井下实测资料为依据，研究了综放面底板采动应力场对跨采巷道的作用，揭示了综放面底板采动应力场的基本特征及其跨采巷道矿山压力显现规律．The thickness of coal, moving scape of over burden rocks and stress caused by fully_mechanized sublevel caving mining are much bigger than that of slice mining. According to the surveyed data, the authors have studied the influence of caving face to roadway in floor, and revealed the behaviour law of ground pressure around roadway under caving face and the basic characteristics of the stress field in floor.

关 键 词：综放开采 跨采巷道 矿压显现规律 采动应力场
