摘　　要：12408E综采工作面属于色连二矿东翼、二盘区首采工作面,地质条件复杂,面内共发育大小断层共14条,落差0.8~4.2m,对工作面的安全回采、原煤质量造成重大影响,对机电设备检修、维护提出了严峻的考验。文章研究了如何合理地选取过断层方法,通过工作面过断层的实践,总结了针对过落差大、数量集中、揭露面积大的断层群的回采技术方法,实现了安全、经济、高效过断层,为相似地质条件下的中厚煤层综采工作面过断层提供了参考。12408 E fully mechanized mining face is the first mining face in the east wing second panel of Selian No.2 Coal Mine.The geological condition is complex with 14 large and small faults,a drop of 0.8~4.2 m,which have a significant impact on the mining safety,raw coal quality,and the maintenance and repair of mechanical and electrical equipment.So it is important to select reasonable fault passing method.Through the practice in this working face,the mining technologies for the passing though large-drop concentrated fault groups with large exposed area are summarized,to provides references for fully mechanized working face to pass through faults safely,economically and efficiently in the medium thick coal seam under similar geological conditions.
