摘　　要：运用地质雷达探测技术并结合现场钻孔勘测、地表观察以及理论分析,对乌东煤矿北采区+575 m水平43~#煤层东翼工作面和45~#煤层东翼工作面的采空区顶板垮落情况进行研究,从而掌握工作面上覆岩层的垮落情况,弥补了之前采取的爆破、注水等卸压措施的不足,为工作面的安全生产提供了依据。Using ground penetrating radar detection technology and combining with field drilling exploration, surface observation and theoretical analysis, to the north mining area of Wudong coal mine ＋ 575 m level 43# coal seam east wing working face and 45# coal seam east wing working face goal roof caving conditions is studied, so as to master the two caving of overburden stratum at the working face, has made up before blasting, water injection pressure relief measures, provide the basis for safety production of working face.
