摘　　要：以3304综放工作面过FQ29断层为研究背景,通过对该断层产状和落差的分析,提出了合理过FQ29断层技术方案,并结合现场开采中对断层的揭露情况,验证了理论计算的该断层延伸速度和方向与实际揭露情况基本一致。过断层期间采用合理的层位控制、断层破碎区域铺设金属网等措施,通过了FQ29断层构造影响区,保证了3304综放工作面生产的安全稳定。With the research background that No. 3304 fully mechanized caving face passed through FQ29 fault, the technical proposal of passing through FQ29 fault reasonably was put forward according to the analysis of fault occurrence and fall combined with the fault exposing situation in mining field, it verified that the theoretical calculation of the fault＇s extending speed and direction were basically the same with actual situation. By adopting reasonable horizon control and metal nets in broken zone of the fault, the working face passed through the affected zone of FQ29 fault successfully, which ensured the mining safety and stability of No. 3304 fully mechanized caving face.
