摘　　要：承压水体上大倾角煤层综采工作面围岩运移规律复杂,论文采用物理相似模拟实验研究手段研究底板在承压水作用下,大倾角煤层开采时,顶板岩层的运移是一个空间问题,沿工作面自上向下采空区充填特征为:空顶区、部分充填区、完全充填区、压实区;底板在承压水作用下,易在回采巷道范围内形成压剪裂隙、张拉裂隙,该裂隙可成为导水通道;研究底板在承压水作用下裂隙发展及分布规律对该类煤层安全开采具有指导意义。Confined water in large dip Angle of coal seam fully mechanized coal face migration regularity of surrounding rock is complex, thepaper USES the physical analog simulation experiment research methods base plate under the action of confined water, large dip Angle of coalseam mining, the migration of roof strata is a problem of space, along the goaf filling characteristics as follows： face downwards on empty area,partial backfilling area, packing area, compaction area completely; Plate under the action of confined water, easy to form within the scope of thestoping laneway press shear fractures, tension cracks, the crack can be guide water channel; The floor under the effect of confined water frac-ture development and distribution of the coal seam has guiding significance for safe miningo
