摘　　要：为了确保综采工作面在过夹矸段可以安全高效回采,需要重新调整回采方案,制定行之有效的技术方案。华亭煤矿250101-2工作面通过研究夹矸层的岩性、形状、长度及落差,并实施过夹矸段挑顶工艺,避免工作面采煤机大范围截割夹矸层,确保了工作面的顺利回采,同时为类似工作面的开采积累了宝贵经验。In order to ensure the safety and efficient mining passing the gangue interlayer in the fully mechanized mining face,it is necessary to readjust the mining plan and make effective technical plan.In 250101-2 working face of Huating coal mine,according to the lithology,shape,length and drop of gangue interlayer,and through carrying out the roof-lifting technology of gangue interlayer,the shearer can avoid cutting gangue interlayer in a large scale,it ensures the smooth mining of the working face,and at the same time,it has accumulated valuable experience for the mining of similar working face.
