摘　　要：53下05(北)是济宁三号煤矿五采区的孤岛综放工作面,地质条件复杂,针对工作面压力较大,围岩变形严重的实际情况,研究了本面与其相邻采空区覆岩空间结构形式及其运动方式,给出了采场覆岩空间结构运动与矿压显现特征规律。53 under 05（North） is an island top coal caving longwall face in the #5 mining district of Jining No.3 Mine.This island top coal caving longwall face is characterized of complex geological conditions with substantial rock pressure at the face.To cope with these situations,a study is made on the spatial structure and the movement pattern of the overlying strata over this island face and the adjacent gob area.In this way,the regularity of spatial structure of the overlying strata over the mining face,the movement patter of the overlying strata and the characteristics of the mine behaviours become known.
