摘　　要：岱庄煤矿井田范围内冲积层相对较厚,基岩相对较薄,开采后影响地表的范围及地表危险移动边界不确定。本文通过对4个岩移观测站的数据进行了整理和分析,确定了厚冲积层条件下岩移观测的边界角和移动角,使得今后预计的采动影响范围更加精确,为以后工作面布置提供了可靠的依据,更好的指导了生产。The alluvia of Daizhuang Mine coal is thicker and the bed rock is thinner, the scope and boundary of surface movement after mining is dubi- ous. This paper well - establist how to get boundary angle and displacement angle under thick alluvia through analysing the g observation stations＇ meas- ured data. This achievement will make the forecast of mine scope and influence more precise. It also can be used as a basement on aranging working face.
