摘　　要：以鹤岗矿区富力煤矿62184工作面为背景,开展了坚硬顶板多煤层开采动力灾害(矿震和矿震诱发的冲击地压)治理技术研究。根据已发生的多次冲击显现分析了坚硬顶板多层煤开采条件下冲击地压发生原因。根据微地震监测数据确定了对工作面冲击危险产生主要影响的坚硬岩层。提出从降低静载荷、削弱动载荷、增强抗冲能力、完善冲击危险性监测预警4个方面开展针对性的冲击地压综合治理工作,以此为依据制定的冲击地压防治措施在现场施工后起到良好效果。Taking Fuli Coal Mine 62184 working face in Hegang mining area as the background,we carried out dynamic disasters control technology research for hard roof multi-layer mining（ mine earthquake and rock burst induced by mine earthquake）. By the analysis of several rock-burst reasons in hard roof multi-layer mining,according to the micro seismic monitoring data,we determine the hard seam that has main influence on rock burst danger,and propose comprehensive control measures of rock burst from four aspects：reducing static load,weakening dynamic load,enhancing anti-rock burst ability,perfecting monitoring system. The measures established by the research results ensured the safety of 62184 working face.
